Thank you for your response and link….very much appreciated.
John himself was born Fremington or Grinton, Yorkshire.
I believe John White's parents were John White (b circa 1781) and Deborah Peacock (b circa 1781). His siblings were Agnes (b. 1802), Mary (b. 1804) and Ruth (b. 1806)
His grandparents were William White and Elinor Thwaits.
It may be that their children's names come from his side of the family?
I couldn't find anything to indicate that there had been earlier children who may have died, but obviously that's not to say there wasn't.
They didn't marry young - John (batchelor, 31, footman) and Helen (spinster, 29, laundry maid) married at St Mary's Church in Hornby on 3rd June 1840. Both were living in Hornby at the time of their marriage. His father, John was a husbandman. Her father, Alexander was a Parish clerk
Would so love to find a lead on this Scottish ancestry!
