Finding a middle name is a task in itself, so I know many people resort to filler middle names. What names do you consider to be filler middle names? Thanks. 
[name_f]Marie[/name_f]
[name_f]Elizabeth[/name_f]
[name_f]Rose[/name_f]
[name_f]Grace[/name_f]
[name_f]Belle[/name_f]
[name_f]Paige[/name_f]
[name_u]June[/name_u]
[name_f]Anne[/name_f]/[name_f]Ann[/name_f]
[name_f]Juliet[/name_f]
[name_f]Claire[/name_f]
[name_f]May[/name_f]
[name_m]Peter[/name_m]
[name_u]James[/name_u]
[name_f]May[/name_f]
[name_f]Jane[/name_f]
[name_f]Rose[/name_f]
[name_f]Grace[/name_f]
[name_m]David[/name_m]
[name_u]James[/name_u]
These are the ones that immediately come to mind. I’ll probably think of some more later.
For girls: [name_f]Ann[/name_f], [name_f]Grace[/name_f], [name_f]Marie[/name_f] and [name_f]Rose[/name_f] are the biggest ones. Also [name_u]Lee[/name_u]/[name_u]Leigh[/name_u], though that’s used less lately. [name_f]Claire[/name_f], [name_f]Hope[/name_f] and [name_f]Mae[/name_f] are also kind of heading that way.
For boys: [name_u]James[/name_u] and [name_u]Michael[/name_u] are the only ones that immediately come to mind.
[name_f]Marie[/name_f], [name_f]Elise[/name_f] and [name_f]Nicole[/name_f]
[name_f]Jane[/name_f]
[name_u]Jean[/name_u]
[name_f]Rose[/name_f]
[name_f]Marie[/name_f]
[name_f]Anne[/name_f]
[name_u]Lynn[/name_u]
[name_f]Nicole[/name_f]
[name_f]Elizabeth[/name_f]
[name_f]Grace[/name_f]
[name_f]Elise[/name_f]
[name_f]Hope[/name_f]
[name_f]May[/name_f]/[name_f]Mae[/name_f]
[name_u]James[/name_u]
[name_u]Michael[/name_u]
[name_m]David[/name_m]
[name_m]Kenneth[/name_m]
[name_m]Christopher[/name_m]
I’m surprised that so many people think [name_f]Elizabeth[/name_f] is a filler! I’ve only met one person (that I know of) with the mn [name_f]Elizabeth[/name_f]. Maybe it’s just my area 
[name_f]Rose[/name_f]
[name_f]Grace[/name_f]
[name_f]Anne[/name_f]/[name_f]Ann[/name_f]
[name_f]Elizabeth[/name_f]
Though, I still like [name_f]Rose[/name_f] and [name_f]Grace[/name_f] and would personally use them for reasons other than just as a “filler”
And a few from girls my age, though not heard as much now:
[name_f]Nicole[/name_f]
[name_f]Marie[/name_f]
[name_u]Lynn[/name_u]
I’m sure these have all been covered, but here’s my two cents.
[name_f]Ann[/name_f]
[name_f]Belle[/name_f]
[name_f]Elizabeth[/name_f]
[name_f]Grace[/name_f]
[name_f]Kate[/name_f]
[name_f]Louise[/name_f]
[name_u]Lynn[/name_u]
[name_f]Marie[/name_f]
[name_f]Rose[/name_f]
For boys, [name_u]James[/name_u] is pretty common. Which is unfortunate because that’s my husband’s name and we’ll probably use it as a middle for our first son!
[name_f]Elizabeth[/name_f] is my middle name. But it’s a good filler because it’s a classic with more “guts” than some shorter middles. I went to school with so many girls with the middle name [name_f]Marie[/name_f]. And [name_f]Rose[/name_f] is currently the queen of all filler middle names! However, I think most of these names would be gorgeous as firsts because they’re so underused.
[name_f]Anne[/name_f]
[name_f]Grace[/name_f]
[name_u]Lynn[/name_u]
[name_f]Marie[/name_f]
[name_f]Mae[/name_f]
[name_f]Pearl[/name_f]
[name_f]Rose[/name_f]
And to a much lesser extent, as I feel it is a name that works no matter where you put it:
[name_f]Elizabeth[/name_f]
[name_f]Marie[/name_f]
[name_f]Jane[/name_f]
[name_f]Rose[/name_f]
[name_f]Grace[/name_f]
[name_f]Elizabeth[/name_f]
[name_f]Ann[/name_f]
[name_f]May[/name_f]/[name_f]Mae[/name_f]
I’m guilty of using one of these as a middle name, but I wanted to give my daughter the same middle name as me. Despite their “filler” status, I think all of these names are very pretty.
Honestly, I love some of the “filler” names, like [name_f]Jane[/name_f] and [name_f]Belle[/name_f]. I’d probably use this list:
[name_f]Marie[/name_f]
[name_f]Mae[/name_f]/[name_f]May[/name_f]
[name_u]Lynn[/name_u]
[name_f]Rose[/name_f]
[name_f]Grace[/name_f]
[name_f]Ann[/name_f]
[name_f]Jane[/name_f]
[name_u]Jean[/name_u]
[name_f]Kate[/name_f]/[name_f]Katherine[/name_f]/[name_f]Catherine[/name_f]
I feel like boys have fewer filler middle names, and it seems like they are more frequently family names or classic/popular names. [name_u]James[/name_u], [name_m]Jacob[/name_m], [name_m]Robert[/name_m], [name_m]Matthew[/name_m], etc. Those seem less like filler names to me for some reason.
Most of the little girls we know right now have the following middle names:
[name_f]Rose[/name_f]
[name_f]Grace[/name_f]
[name_u]Grey[/name_u] (oddly enough)
The vast majority have [name_f]Rose[/name_f] as a middle name. Probably 80%. Then most of the rest have [name_f]Grace[/name_f] as a middle. We know at least three little girls with [name_u]Grey[/name_u] as a middle (and it is not a family name in any of these cases) which makes me feel like its a filler. We are in the Southeastern US, if that helps. Many people tend us to use the mothers maiden name as a middle here. [name_f]Virtue[/name_f] names are also popular as middles (predominantly [name_f]Faith[/name_f], [name_f]Hope[/name_f], and [name_f]Grace[/name_f], though [name_f]Grace[/name_f] is by far the most popular.)
I always thought of [name_f]Rose[/name_f] as filler, but we ended up using it for our daughter’s middle name to honor my husband’s deceased grandmother, and now I find it so beautiful.
I think one person’s “filler” middle name is another person’s beloved middle name.
My middle name of [name_f]Diane[/name_f] felt a bit fillerish to me until I remembered that it was my Dad’s special choice for me.
[name_f]Marie[/name_f] would be filler for me or [name_f]Ann[/name_f], but that is because I don’t like them. [name_f]Jane[/name_f] or [name_f]Anne[/name_f] would not be filler, because i like them.
I don’t think their are any filler middle names my middle name is [name_f]Anne[/name_f] but its a family name, you can’t just discount a name as a filler. My sisters middle name is [name_f]Louise[/name_f] because it sounds nice with [name_f]Adele[/name_f]. I will use [name_f]Anne[/name_f] and [name_f]Grace[/name_f] as middles because they are family names and I would use [name_f]Rose[/name_f] because the two names I would pair it with are quite heavy.
What are commonly believed as fillers:
[name_f]Rose[/name_f]
[name_f]Marie[/name_f]/[name_f]Maree[/name_f]
[name_f]Jane[/name_f]/[name_f]Jayne[/name_f]
[name_f]Anne[/name_f]/[name_f]Ann[/name_f]
[name_f]Claire[/name_f]
[name_u]Lee[/name_u]
[name_u]Jean[/name_u]
[name_f]Elizabeth[/name_f]
Boys the only one I can think of is [name_u]James[/name_u] which I would use for family reasons
[name_f]Marie[/name_f], [name_f]Rose[/name_f], [name_f]Elizabeth[/name_f], Grave, [name_f]Jane[/name_f], [name_f]Maria[/name_f]
[name_u]James[/name_u], [name_m]Alexander[/name_m]
[name_f]Marie[/name_f], [name_f]Jane[/name_f], [name_f]Grace[/name_f], [name_f]Elizabeth[/name_f], [name_f]Rose[/name_f]
[name_u]James[/name_u], [name_m]Alexander[/name_m]
[name_f]Rose[/name_f], [name_f]Marie[/name_f], [name_f]Jane[/name_f], [name_f]May[/name_f], [name_f]Grace[/name_f]
[name_u]James[/name_u]
I know a lot of little girls with the middle name [name_f]Faith[/name_f]. I didn’t consider [name_u]Shea[/name_u] a filler, until I gave it to me daughter and have since met several girls of all ages with that middle. I liked it because it honors my brother [name_u]Shane[/name_u].
