I am researching Hophni Flanders and stumbled upon this. I, too, am struggling in identifying Betsy. Thank you for this.
My question revolves around the fact that Betsy and Hophni had their first child in 1797. She would have been 17. Hophni was born in 1746. There creates quite an age mismatch. How certain is the identification of Betsy as daughter of John and Elizabeth?
