Looking For: Marriage William Callear (b.1765) to Sarah ? (b. 1786)

[SiCallear]

Hi,

Can anyone help:

I'm looking for a record of a marriage of William Callear (b. ~1765) to Sarah ? (b. ~1786)

They are shown as living together on the 1821 census with what I believe to be a mix of children from William's first marriage to an Hannah Jones and his 'marriage' to Sarah.

His children with Sarah are:

Samuel b. ~1812
Martha b. ~1814
Mary Ann b. ~1819

Thanks for your help (and for even taking the time to read this!)
