Thornton le Fen is both a parish and a scattered township which lies 6 miles northwest of Boston. Carrington parish is to the northeast and Langrick parish to the southwest. The parish includes the hamlet of Bunker's Hill on the Howbridge Drain, and covers about 1,670 acres.
This is more than 10 miles South of Moorby....but later censuses suggest that John Lowis came from even further south- Cambridgeshire.
