Don't know if you are still seeking info but a lot of what you have matches my mothers family (Perry) I can't find the attachment but my grandfather George E Perry was born in Oswego, NY and was married to Agnes who s=died in the early 50's of a heart attack. They had 3 daughters Rita, Shirley and Florence, Shirley and Florence remained in Oswego their entire lives. George remarried a woman named Ruby and they relocated to Tampa Florida.
I too am seeking information, my mother (Rita) didn't have a close relationship with her family upon leaving home and would not speak about her childhood. I did have the opportunity to meet Shirley and her children once but never knew my grandfather George. I am attempting to work on a Perry geneology but am hitting a brick wall...Anyone with information please feel free to contact me, it would be greatly appreciated!
