There is Robert Bertram James in 1851 census. Age 31, Glassmaker, b. North Shields. Married to Betsey Barker and living with in laws in Lancs. In 1841, he is living with same family in Lancs, Robert James, Glass Maker, age 20, Not born in County. By 1861, Betsey is a widow.
Their 1841 marriage on Familysearch has Roberts father as John. Do you have copy of the marriage cert, which will be good help in identifying Roberts baptism, as it should give his fathers occupation? The only mention of Roberts middle name as Bertram seems to be the 1851 census.
There are two John James having children baptized at Tynemouth (Parish Church for North Shields) at about the right time. John and Ann and John and Eleanor, but no son Robert there.
There is :
31st March 1820. Jane James, daughter of John (Glassmaker) and Ann, of Low Lights.
There is a baptism of a Robert James at Heworth St. Mary.
9th May 1818. Robert James, son of John (Glassman) and Anne, of Bill Quay.
Only a few miles across the river and upstream from North Shields.
Its a big leap back to the John and Ann marrying in Earsdon in 1792 though.
Merry Xmas.
