Only Suffolk birth / death I've found is probably the one you refer to in your post....
Dorothy Jessie Nicholls born 12 Aug 1887 Blything, Suffolk - died 1974 Ipswich.
Blything and Westleton seem to be about 17 miles apart and equidistant from Bury St Edmunds.
As I don't know the area / parishes, I cant comment on the likelihood of whether all these results refer to the same person, or 3 different Dorothys.
