Attempting in 2014 to prove or disprove the Fant, Faunt,L'enfant family as a single origin family, I am getting a huge amount of families in my assorted databases. I find families in Lincolnshire, Rutland, Nottinghamshire, Leicestershire, Northamptonshire,Derbyshire and a bit of Staffordshire pretty far back in time.
The family which Ernest Albert Fant originated in first comes to my attention in Lincolnshire. Robert Fant, father of Ernest, is apparently born to a single mother in Spalding, Lincolnshire. This Martha Fant born in Gosberton also has sons John Thomas and William Laycock Fant. Was there a William Laycock who she married before she marries William Burwell in 1859? If so I cannot find him although it is surely possible. Her father was Thomas Fant from Upwell Cambridgeshire and her mother Elizabeth Carteron. She has a brother Thomas who in 1849 goes to jail for larceny for 2 months and seems to die without issue.
So Ernest Albert Fant and his progeny who eventually are found in Nottinghamshire and perhaps even in Hull. Perhaps they would not be DNA matches as their male line seems to be handed down differently than the Fant surname.
There is also a group from Yorkshire and Westmorland but that may be for another day, although the areas sort of drift into one another.
