There is a marriage in Sunderland, 7 Feb 1793, of John Laws and Lydia Mills.
Then a birth/baptism in Sunderland, John son of John and Lydia Laws, born 9 Nov 1793, baptised 16 Feb 1794.
This is highly likely to be the John Mills Laws in Diddys post marrying Ann Gourlay in 1816.
I can't see another John Laws baptism in Sunderland around this time. There is a baptism of a John Laws in Newcastle All Saints on the stated date of 21 April 1793. Is this the baptism referred to? If so he's the son of George Laws, Pitman, and wife Jane.
John Laws and Ann Todd have at least 4 children baptised in Sunderland. Robert and George as stated, also William Laws, b. April 12, baptised June 11 1815, and Ann Laws, b. Oct 18, baptised Dec 24 1820.
This overlaps the marriage of the other John Laws and Ann Gourlay so we are looking at two different Johns and Anns. I've checked the last two baptisms of John Laws and Ann Todd on the Bishops Transcripts and John is down as a Coachman.
Jonny, who is your ancestor that we are looking for? Is it one of John Laws and Ann Todds children, or is it someone connected to the John/Ann from 1841? John and Ann in 1841 have a Lydia and Jane Sidgwick, 24 and 18mo living with them, perhaps their daughter and granddaughter?
