Thomas and Mary Collingwood

[Sue from Southend]

Thomas and Mary Collingwood baptise two children at St Ann’s Blackfriars in 1803 (Thomas) and 1808 (Mary) although the latter was actually born in 1801.

Can anyone find a marriage for Thomas and Mary? I’m wondering if he is the Thomas Collingwood named in his father’s will in 1799 with a d.o.b. helpfully given as 31 Aug 1774 (I can’t find a baptism for that either!) The will mentions property in Huntingdonshire so marriages, births etc might be there or in London but I can’t spot them. The will:-

“My” Mary Ann Collingwood stated in 1861 that she was born 1801 in Bishopsgate so this baptism has been on my radar for a while but a recent DNA match from the right branch of the family has Collingwoods originating in Huntingdonshire. I'm hoping to find a link somewhere.....
