Hi Delen,
Gt Saxham, Risby
Great Saxham or Little Saxham may have had a mill in about 1280. Records very sketchy. Check out “A History of the Abbey of Bury St. Edmunds”, (Woodbridge, 2007).
Same source suggests Risby had a mill too at the same time, and a windmill was granted to Abbey of BStE by Ralf le Breton in 1200, see 1 P.R.O. MS. D.L. 42.5 (Bury Cellarer’s Cartulary), fol. 42v.
Hope this helps and it you find anything else I'd be grateful if you could tell me so I can added it to my db.
Cheers,
Windy
