Whilst searching RootsWeb today (another valuable resource), I came across a page which suggested I had made another mistake on an ancestor’s surname.
I had my gt(x3)-grandmother as Ann MEASBY, but the new source suggested it was MEASDY (or MEASDAY). I rechecked her marriage certificate (which I have), and sure enough, I had misread the (poor) handwriting for the father’s (sur)name. Double-checking the witnesses confirmed them as Sarah MEASDY and Charles MEASDY, not the former MEASBY.
Never assume you’re wrong, but never believe only you could be right … I was fortunate enough to have the certificate to double-check and confirm the new source information.
I will update the tree accordingly soon.
