A postscript to my original message. My copy of the Thwing parish registers only goes up to 1812, so I had a look online for later Coultas records. I think I was wrong in assuming the last two children, Richard and Bessey, were your Robert and Jane's. Further children were born to Robert and Jane Coultas: Mary and Ruth (1814), Robert (1817) and Tamar 1822 - in the same time period as Vickerman Coultas's children were being baptised. I suggest this Robert could be Vickerman's brother or cousin. Robert is described as a labourer.
Anyway, you believe your RC was died in 1820. Plus, if the Bridlington marriage is the right one, that would be a 40-year child-bearing period! Clearly I wasn't thinking straight.
I note there is a marriage between an RC of Burton Fleming and a Jane Putsey on 11 Nov 1809 in Ganton. I haven't found Jane's baptism in Ganton. (One was baptised in 1775 in Thorpe Bassett, father John). But I know from my own family research that there were connections between many families in, for example, the neighbouring parishes of Ganton, Willerby, Hunmanby, Thwing and Langtoft, and they moved around. It may be significant that that two children born to Stephen and Elizabeth Putsey (he was a tailor) in Ganton were called Ruth and Tamar.
You might want to check the parish registers of Wintringham for Coultas records.
All the best
