Hi Lauren,
Sorry it took me a year to see this. At this point, it seems you have more information about Agnes than I do. My wife's great-grandmother was Agnes's older sister Madeline. However, she left western PA and moved to the Philadelphia relatively young. My wife's late father did go up to visit his aunts occasionally, so I'll see if I can get anything out of my mother-in-law next time I see her.
Best,
Eric
