Upon a search for the name Alida Holm I came across your post. I doubt there is a connection but one can never tell if one never tries.
The Alida Holm I am looking for married my great uncle Theodor Gustaf (b. 1874). Theodor and Alida had two children... a daughter Vanda b. 1911 in Estonia and a son Gunnar b. 1915 in Finland.
If you happen to come across these names I would very much like to share notes, and I will do the same for you if I come across any names in your own list.
