More than 2 years ago, several of you were very helpful in trying to find a record of the baptisms of Thomas and Matthew Lee, but without success. I think I have now found them - under a slightly different name. I was using the NDFHS database in Newcastle and found among the Brancepeth records the baptisms in July 1825 of Thomas, Matthew and Isabella Leech, children of John and Isabella Leech. I know these were the names of the 3 youngest children. I knew of Isabella's existence from the record of her death - in 1832, I think. She was 15 then,if the burial record is correct, so would have been about 8 at her baptism, quite old for baptism. I suppose it would be quite easy to hear Leech for Lee, especially if their father had rather a strong accent.
I have several ancestors whose baptism records I can't find - I am now trying to imagine how these surnames might be misheard by the parish clerk!
Anyway, thank you to everyone who helped.
