I have complex feelings about
Martha. My grandmother's name is
Martha (
Marta), so I have a really strong and negative association with it as being a cold, cruel, manipulative name with a bad smell. On the other hand, I once knew a cat named
Martha, and that was adorable, so I also think of it as affectionate, warm, and soft. Complicated! I do think that
Martha will become a bit more popular with time - it seems right up hipster alley.
I think you're safe from
Marty. I would instinctively shorten it to Marth...which I'm not sure is much better.
Of your combos, I really like
Martha Emily,
Martha Madeleine, and
Martha Josephine - they really fit with the warm soft side of
Martha I enjoy.
I also quite like
Martha Caroline! :) And
Martha Phoebe. And
Martha Clementine.
Martha,
Susan, and
Elizabeth are ok. I think I'd like
Martha,
Susannah, and
Elizabeth better.
Susan and
Martha together are kind of flat.
Sally and
Betsy are adorable though. Would
Sally be Sally-in-full, or short for
Sarah?
Sarah,
Susannah and
Martha would be a super sweet trio.
I think these would go well with
Martha as sisters:
