I've been looking at Isaacs wife Line.
The IGI shows that Helen Stirling died 11 Dec 1884, mother was Mary Anderson. I looked the cert up, she died in St. Ninians, of paralysis, registered by her widower, Isaac. Mother, Mary Anderson, Agricultural Labourer, no father's name is given.
I think Helen may have been illegitimate and her mother Mary Anderson went on to marry a 'Stirling'
I can find a record of Mary Anderson marrying a James Stirling 30 Jan 1824, 2 years after Helen was born.
Are there any possible records that would verify that Mat marrying James is the same as mother of Helen?
Thanks
