Apology for delay in responding.
My research on the Hogan family beyond Fairfield and Kershaw Co. of SC has only just begun. Apparently, the name William Hogan appears in many different family lines and is requiring careful study to try and separate. My line at present has my ancestors in Chamblee, NC marrying into the Parker family. Once they arrived in SC Hogans continued to marry Parkers. My Gr.grandmother was a Hogan, my gr.grandfather a Parker.
Union, Fairfield, Kershaw etc. were once part of old Craven District, SC before becoming individual counties and is the area to which many NC Hogans migrated. I am hoping that through Ancestry and DNA studies the real links are made, but feel it will take time.
When time permits I go to Winnsboro and Camden, SC to research and will keep updating my Hogan info on Ancestry.
