I’ve noticed a couple names that seem to be either/or names — meaning, if you use one for one child, it seems the other is really not usable for another. I don’t mean like Oliver and Olivia; I mean names that *are* different, but *just* too close. Like:
Theodore and Thaddeus
Evangeline and Genevieve (and Vivian/Vivienne)
Magdalene and Margaret
Theodore and Thaddeus both start with Th-, both have a d in the middle, and can both be nicknamed Ted/Teddy. Evangeline and Genevieve both have lots of v and n and soft g sounds happening, and both can be nicknamed Evie. Vivian/Vivienne strikes me as belonging to that group too, but Evangeline and Genevieve really seem two sides to the same coin to me. Magdalene and Margaret have the M and the g and can both be nicknamed Maggie.
But even as I think they’re too close to each other to be used for different-age siblings within a family, I could see them working quite nicely as twin names — a nice connection without being too matchy:
Theodore could be Theo and Thaddeus could be Taddy
Evangeline could be Evie and Genevieve could be Genny
Magdalene could be Lena or Maggie and Margaret could be Maggie or Greta
One hitch with this twin idea is that these names seem to represent slight but significant differences in taste. For example, it seems to me that people either prefer Theodore or Thaddeus — they don’t like them equally. Another pairing that makes this even more obvious to me is Sophia/Sophie and Sylvia/Sylvie — it seems to me that a person would prefer either the Sophi- names or the Sylvi- names, and whoever would choose the Sylvi- names likely wouldn’t be at all inclined to choose a Sophi- name, and vice versa.
Does this make sense? Do you get what my thought process is here or is it crazy? Can you think of other names like this?
