I absolutely would love to use the name [name_m]Paul[/name_m] to honour my father however to add a more modern twist to the name I’d use the nickname [name_u]Pip[/name_u].
I’m stuck on sibling names - [name_m]Paul[/name_m] is quite an old name now but I don’t want names that are stuck in the past if that makes sense!
[name_f]Do[/name_f] you have any names you think would work with [name_m]Paul[/name_m] or [name_u]Pip[/name_u]? 
I’ve always loved the name [name_m]Paul[/name_m]. Unfortunately, it doesn’t work with our last name.
The two (baby) [name_m]Paul[/name_m](s) I know are
[name_m]Paul[/name_m] [name_m]Abel[/name_m] & [name_m]Paul[/name_m] [name_m]Morrison[/name_m]. I love both of these combinations!
Another favorite is [name_m]Paul[/name_m] [name_u]Bennett[/name_u].
Paul “[name_u]Pip[/name_u]” is such a sweet idea!
For sibling names, I like the idea of following a similar pattern of a familiar, possibly underused classic with a fun, fresh/unexpected nickname.

Hi there.
Pip is so cute! [name_f]My[/name_f] husband is [name_m]Paul[/name_m], & while we’re not into juniors, I’ve still thought about this. What I’d call a [name_m]Paul[/name_m] [name_m]Jr[/name_m]. I love [name_u]Pip[/name_u], but also [name_m]Paul[/name_m] nn Patch. 
I’m really tempted to suggest older solid names w/quirky nns.
How about…
