It appears from the deeds I transcribed below (not word for word as you can see) which I found in the Rockingham County, NH, Courthouse, that Ann is a daughter of Abraham and the husband of Elizabeth is a brother of Ann.My main interest in is knowing what Ann's connection is to the Vennard family and also who the other three siblings are.thanks.
