Hi Jettie, thank you for the information provided. I will look at the link you gave me shortly. Am just in from work and have to cook dinner first. I know it was a long shot but thought I'd give it a try. It's just that I can't find a marriage for Isabella her in England between her becoming a widow and her marrying another gentleman John Laxton in 1900 in England. She could have perhaps just changed her surname being that she had a conviction, not sure how things worked in those times. She certainly didn't change her first name. Perhaps she might have married aboard ship if they did that sort of thing then? Isabella was born in 1843 (I don't have her exact date of birth) in Hartlepool, Durham, England.
Thank you once again for your time and help.
