I would be interested in talking to anyone who is searching the Charles Groom(s) line. My gg-grandfather Peter Groom married Louisa O'Harra, daughter of Lucinda Legg and Thomas O'Harra.
I believe that Charles (who married Tabitha Wiley whose mother was Elizabeth Legg) may have been the brother of Peter. Charles is shown in the 1850 census with Harmon and Bertha Groom. Peter and his wife are 2 residences away from Harmon Groom. I believe the family came from New Jersey into Franklin Co.
