Tiss, Confusion and working together are expectedtraits of genealogy.Ages of Wm, Sr and Maryare very close to yours.Census are known to be wrong sometimes, soVa. Birth-state could be in error. I’m not 100% that Wm P.’s 1st wife was Eliza.. The census was hard to read but I’m pretty sure it says Eliza.Also youngest child (son) name was hard to make out but think it was Joel C. Happy Hunting.
Marcia Gregory lived in Macedonia Iowa.With location, ages and time of marriage, I’mbetting that the Wm. Dinwiddie in 1880 censusis same Wm. P. Dinwiddie married Marcia.
