Hi
Something else to consider!
Have you seen the children of John Millar and Jane, nee Wilson?
There is a baptism of four of them on 23 January 1804 at Gateshead.
Henry, born 9 April 1790, 4th son
Timothy, born 6 January 1792, 5th son
William, born 9 February 1796, 6th son
Wilson, born 3 February 1798, 7th son
BT here (over two images)
https://www.familysearch.org/ark:/61903/3:1:S3HT-XCQ9-569It says that father John is a Shoemaker, deceased. And in fact he was buried on that very same day at Gateshead, age 50. Died 21 January.
https://www.familysearch.org/ark:/61903/3:1:S3HT-XCQ9-5SYSo John and Jane had three sons born before 1790. Can we find any?
Going back, a double baptism at Gateshead, 18 Feb 1787
John & George, sons of John Millar

https://www.familysearch.org/ark:/61903/3:1:S3HT-XCQ9-G84No mothers names given in Gateshead then. Not on the BTs at least. And of course we can't be sure that is the same John Millar, since the info is so minimal
It doesn't say the are boys twins. They may have been of course, but one of them could have been older.
No Gateshead BT for 1787-8, but from the parish registers FamilySearch have indexed an Esther Millar baptized at Gateshead, 18 May 1788, father John
https://www.familysearch.org/ark:/61903/1:1:J3S3-W8DShe would be a good match on age for the Esther Carr buried June 1839, age 51 (age 50 in the new GRO death index), if indeed that was the Esther Miller who married in 1822. Don't know for sure.
An Esther Wilson, daughter of Timothy, was baptized in Gateshead later in 1788 (is on the 1788-79 BT). Timothy likely had a son Timothy baptized there in 1786
Haven't found a marriage for John Millar and Jane Wilson.
Not everything is perfect here, but the right names are potentially there. Could Timothy Wilson senior have been a brother of Jane Millar? Either he or his son could have been Esther's marriage witness.
