Hi,
I have a John Dinsdale, 1779-1855, he is my 5th great grandfather. I have been unable to get further back and wonder if he was a brother of your relative ? I have his father's marrying a Betty Blythe, but this information is sketchy. My 5th GGF was married to Elizabeth Fawcatt in Aysgarth in 1799, he was born in Buttersett, so the area seems to fit. He was a carpenter.
Is it possible for you to check if this is a link ? It would be amazing to get further back
Many Thanks
