Hi Betty
Esther is in the 1851 census, still a eidow, but I did not find her after that. In 1851 she was on Sand Steet in Ramsey with Ann, Lewis and Catherine.
The IGI marriage recordindicates that her maiden name was Corkill. The I did not come up with any likely Lezare born Esthers in 1800-1805 (her likely DOB).
As for alerts, I get them, but didn't for a while and I do not know if one can turn them on and off.
