I have done quite a lot of research on the Hensby name including a few of the variants such as Hensbie,Hensbey and Hinsby etc. I do have some trees that go from Hensby to Hinsby and back to Hensby and vice versa. You will probably be aware of large concentrations of Hensbys/Hinsbys in Cavenham, Suffolk and also West Acre and Castle Acre in Norfolk. There was a Hamlet of Hensby near Cavenham and you will know of the Hemsby in Norfolk.
