MinMin77 on Family Tree Circles

I have become bogged down with my Vaughan family research. I have a John Vaughan 1803-1871 born Hendrisnock, Pembrokeshire, Wales and his wife Margaret .. 1800-1871.

Their daughter Mary Rosina Vaughan married John Jenkins and their child Frank Vaughan Jenkins married Fanny Davies. Frank Vaughan Jenkins is my great grandfather.

I'm looking for the father of above John Vaughan.
