If she didn't remarry or move there isn't much likely hood of her popping up until her death , also her date of birth is a bit suspect by quite a few years, I can't find a birth either although you don't want that info
Louisa Maud
I have noted the birth date, does change a great deal.I have never seen a birth certificate and I have searched. At the time of marriage she lived in Fulham and her only parent a Doctor, was dead. He had connections with Devon.
Just now I have found a birth date 15/6/1870 Beaminster, Devon. Address in Fulham 89C Fulham Park Gardens.
