It's nice to see new posts on the Peffers board! I'm not sure if Erik visits the board very often so I thought I'd post a response. Your great grandmother Lydia Amanda Peffers is the sister of our second great-grandfather Harvey. I show her as marrying Alexander Martin, but I don't have any information after that.
I've been working on the Peffers line quite a bit since these posts and was also able to find information back to Jacob, which I shared with Erik (we're half-brothers). I wish we could find out Jacob's history, who his parents were, where they were from, but in time I guess that might happen. If you'd like, I'd be happy to share our Peffers line since Harvey with you. They were in the city, then up in Westchester County.
