Have been searching for family relatives for a long time but have had very little luck. My great grandfather was John Herbert Kinvig, he lived in Mill Street Castletown, around 1900. His adoptive mother was Anne Kinvig. She was a widow who lived with her 4 children. Bessie Kinvig was his sister, she remained unmarried until her death around 1960. His biological mother was Jane Clugston, she is believed to have lived around Castletown. her father was John Clugstone. Any help will be much appreciated.
