So let me first state, I'm 64, grew up in England and moved to America in 1982, so English is my first language.
I'm making small wooden Christmas gifts for friends and neighbors. On each I'm personalizing it with their name, such as for me 'The Edwards'.
In my case I don't need an associative plural, e.g. my neighbor's last name is White, so theirs will be "The White's".
Two of these, I'm not sure how to apply the associative plural, so looking for guidance.
