Hi Diana! Did I ever reply to you? For some reason I think I might have missed your posting! Sorry about that.
Well good to hear from you! I'd love to get some extra data from you!
I seem to have Oliver's father's name as Charles Dahlgren and mother Anne . Although I did get that from the 1900 Census, and you know that sometimes those can be off.
I've an old photo of Ida (Isaacson) Dahlgren, with toddler Lyle Dahlgren, if you are interested in seeing it, it's also with Ida's mother and grandmother. Quite a great shot 4 generations. Lyle's perhaps a year or two old, so it's probably taken in the 1908 or 1909 or so.
