Just out of interest here are a few Rom names linked to Lincolnshire:
Heron/Herron/Hearn/Hearne/Herring etc
Boswell/Boss
Young (Herons and Bosses under a different surname)
Winter/Winters often alias Smith or Pierce/Pearse
Gray
Elliott
Brown
Smith
Wilson
Rhodes
Shaw
Loveridge
theres more but that will do for now.
The Herons and Boswells, and Bosses all intermarried, also marrying with the Smiths and Grays, a few marrying into the Winters/Pierces/Wilsons/Browns and so on and so forth.
Winters reputedly cam from North East, The Shaws and Loveridges and Herons from the midlands - Northants and East Anglia, the Rhodes came from Hull (far as I know) the Bosses loved Yorkshire. The Grays one branch settled in Cams and East Anglia, the other in Lincs, The Elliotts from Notts, and the Smiths were everywhere.
