I have a huge database of Ferrar/Farrars and there are some Woodsons, Randolphs and Royalls in it.
I am descended from Katherine Banks great granddaughter Sarah Farrar via Her first marriage to Joseph Royall, their daughter Katherine married Richard Perrin, their dtr Katherine married Maj Thomas Farrar, son of Col William Farrar and grandson of Councillor William Ferrar (Farrar), arrived aboard Neptune in 1618, his son Col William inherited the land which is now known as Farrars Island, only to be sold to Thomas Randolph in 1727, Thomas was a brother of William Randolph who married Mary Isham, dtr of Capt Henry Isham and Katherine Banks (her second husband), William and Mary Isham were great grandparents of Thomas Jefferson.
Sarah Farrar married her cousin William Farrar IV, son of William III brother of Thomas Farrar who married Katherine Perrin.
So which Royall are you descended from. Joseph Royall m. Katherine Banks or Mary Royall m. Josiah Woodson.
I am desperately trying, without success to trace Mary Royalls ancestry beyond her parents.Joseph Royall and Elizabeth Kennon.
My mtDNA is haplogroup "J"asmine. A woman born 10,000 years ago in the fertile crescent as her daughters migrated out of that region, they carried with them agriculture and the neolithic (New stone age). My mother was a "yankee", my father a Marine born in Arkansas. My Mothers, mother, mother, mother was born in Prussia.
mtDNA is useless for genealogical purposes.However Family Tree DNA has a Family Finder test, which uses autosomal DNA to connect you with cousins. I have over 35 cousin matches but so far have only been able to establish a connection with one.Others have more luck.
