Wigan Genealogy

I’ve just discovered I have SIMKIN ancestors and am trying to find out more. I know very little so far, in fact all I have is a baptism for my 4 x great-grandmother whose mother was a SIMKIN: Baptised: 25/03/1810 (St. Thomas, Ashton-in-Makerfield). Born: 08/02/1810 Betty 2nd child 1st illegitimate daughter of William WOOD, Ashton, hingemaker & Betty SIMKIN d & w (sic) William SIMKIN. Betty SIMKIN/WOOD went onto marry John COTTAM in 1827. Just putting my SIMKIN feelers out there to see if anybody can help or make a connection.
