Hi both,
With an interest in this because Matt's Charles Taplin links in with my Sellwoods, a word of caution.
Take care. Don't get too carried away before you have proof of the relationship between Charles and William Taplin.
According to the IGI, Charles Taplin was the son of William and Mary bap 1811, whereas William was son of William and Martha bap 1809.
The IGI could, of course, be wrong, or one of them be a mistranscript, or Father William married twice. Only the original Parish Records for Basildon would show that.
Good luck at the RO, Matt.
