Hi Douglas,

Thanks for your response. I had picked up on some of your family from some of the Taggart wills that have been published. The little bit I know about the family of my ggg grandmother Sarah Taggart is that her parents were John Taggart and Esther Quinney, married in Arbory around 1785 - and moved to Malew in ca 1794. After 3 years of fruitlessly trying to identify Sarah I spotted her name on a Taggart will by accident as I was scrolling through an LDS film of wills from 1795! Another will proved her identity. This John Taggart is of the right sort of age to be a brother of your William - do you have any more information on his possible siblings.? It does look as if this is the same family group however.
I'll keep chipping away trying to find out more from other wills and parish records and let you know of any progress. Thanks again.

cheers
