I too am related to John Winterscale, who died in Edinburgh in 1858. He was my great great grandfather. According to his military records in the National Archives at Kew he was born in Sligo in Ireland on 28 July 1788.
My great grandmother's death certificate states that her father was John Winterscale although he never married my great great grandmother Jane Hutchison. My great grandmother was Elizabeth Winterscale who was born on 3 July 1836. As far as I can see he had no contact with his illegitimate daughter.
If this is of interest then let me know
