Just tying up some loose ends, and horrified to realise it looks like I have never replied to your post!
I have Wastells in both maternal and paternal lines, all from Durham area, and currently trying to prove or disprove a link prior to my parents!
My maternal 2 x great grandmother was Annie Laurence Waistell Belton, daughter of Jane Ann Wastell (I think! - currently awaiting birth certificate to confirm). On paternal side my 4 x great grandmother was Elizabeth Wastell, daughter of Robert and Margaret Shirtliffe.
Still v keen to receive any information you can share, and I can likewise email across a report at any time.
