That Jacob might be too early since the probate was in 1892. Is your Jacob from Jefferson, Ashtabula, OH and if so, what line is he from?
As for the people in the photo album, we know the immediate family of Cassius GLEASON and Cora Gillis GLEASON and their sons Harold and Raymond. Raymond's friends I don't know. The elderly women in the pictures would most likely be Ruth Chapin RUGGLES who was the aunt of Cassius GLEASON and is noted in the note that was attached to the album. One of the other women may be Cora Gillis GLEASON's sister Maude Gillis RINARD. The reason we suspect this is because her husband William RINARD died in San Diego, California. So that's as far as we have gotten.
