I, too, am looking for a baptism of a John Skerrett(several variations of this surname, who according to census records was born approx 1816 at Longton. On his death cert, which was in Scotland, he states his parents as Joseph Skerret, potter, and Essex Thomson. Rather an unusual christian name, but it was handed down throughout the family.
I am, of the opinion, that maybe John was illegitimate. Are you able to help. Many thanks.
