Pamela - Yes, I am decended from John's brother Myles. His daughter Bridget married Lawrence Conway and had a very large family, most of whom came here to Scotland in 1850s/60s. Their son John is my Great gt. Grandfather.
The extract below, from Hillary Andrew's book states that Myles died leaving a young family, which would suggest that Bridget had siblings, but I have no information on them. From Bridget's death registration I know that Myles was a farmer and her mother was Mary Surdwell.
The extract below also mentions Thomas and Edward.
