I love this name. It does seem a bit buttoned up though.
What nns would you use other than the standbys?
Instead of:
[name]Matty[/name]…?
[name]Marti[/name]…?
[name]Mae[/name]…?
To me, a leap isn’t forbidden, I think, [name]Tess[/name] and [name]Etta[/name] can come from [name]Esther[/name]. As long as it stays within the realm of connection.
I would love to find a way to really love this name.
I suppose maybe just calling her M? Almost like [name]Emme[/name] or something. I feel like [name]Matty[/name], [name]Marti[/name], or [name]Mae[/name] would be the stretches as nick names for [name]Martha[/name]. Though it would be darling to name her something like [name]Martha[/name] [name]Elizabeth[/name] and use her initials M.E. and call her [name]Emmy[/name]. I had a name with the initials L.C. on my list with the plans of calling her L.C. (like [name]Elsie[/name]) cause I thought it was adorable.
I can’t think of any other nick names though… [name]Mari[/name]? [name]Artie[/name]?
[name]Patsy[/name] and [name]Mattie[/name] are the most common nicknames for [name]Martha[/name] that I’ve seen. I love [name]Martha[/name] as well, but I wouldn’t use a nickname for it. It’s only two syllables (and so are most of the nicknames).
The only one I’ve really heard is [name]Marti[/name]… which could be cute.
[name]Patty[/name] from [name]Martha[/name] is VERY old-fashioned and would probably confuse the hell out of people nowadays, but it is traditional and you can always tell the people who say it doesn’t make any sense, that it is quite historically valid. 
[name]Arty[/name]? [name]Hatty[/name]? [name]Maree[/name] (mah-ree)?
You could call her [name]Art[/name] which is quite cool and cute. [name]Martha[/name] sounds a bit like [name]Arthur[/name] and [name]Art[/name] is a nickname for it.
I would also suggest [name]Mimi[/name] and [name]Mamie[/name].
I like [name]Martha[/name] as-is and would use it like that, though I reckon it would probably get shortened to [name]Marth[/name] unless there was an established nickname in place.
[name]Mimi[/name] could work, or [name]Mar[/name]-[name]Mar[/name], or Ma-ree ([name]Mari[/name]/[name]Maree[/name]/Marey could all work as spellings) or even something completely disconnected like [name]Midge[/name] or [name]Mags[/name] or [name]Mitch[/name]. Or just something combined with her middle.
These suggestions are great!!
I love:
[name]Patsy[/name]
[name]Patty[/name]
[name]Art[/name]
[name]Maree[/name]
[name]Mamie[/name]
Hatty and [name]Midge[/name]?! So adorable. My favorites so far!!
I knew a [name]Martha[/name] who went by [name]Molly[/name] and I thought it was really cute. No one ever questioned it.
I’m loving the idea of [name]Marti[/name]. It’s familiar, but not common. Kind of swooning over the name.
I love [name]Martha[/name]!
[name]Mae[/name] or [name]Marty[/name] would be cute.
I knew a [name]Martha[/name] at school who went by [name]Minty[/name] and I really like it.
[name]Hattie[/name]/[name]Hatty[/name] and [name]Midge[/name] are darling! I, too, love [name]Martha[/name], and these new nn options are bringing a bit of spark to such a traditional name.
[name]Just[/name] use the full name, [name]Martha[/name]…pretty and short already.
I adore [name]Martha[/name] as it… no nickname needed:-)… if i just had to use one, I would go with [name]Marty[/name]
My BFF is [name]Martha[/name] and her family calls her [name]Marcy[/name]. I think it’s adorable.
My great aunt is a [name]Martha[/name], she goes by “Mot.” Not sure tje origin of that nickname. She was born in the 1920’s.
My name is [name]Martha[/name]. I’ve never used a nn, and no one has ever pinned one on me. The pp had a cute idea of using an E middle name, like [name]Martha[/name] [name]Elizabeth[/name], with the nn [name]Emmy[/name].
