the 1851 census pointed out by osprey has head of household John Thomas, wife Hannah Thomas, daughter Susanah Thomas, age 11, and foster son David Found. If this is same family, Rachel Thomas would be age 15 in 1851 census. She is not in the household.
I've located a possible marriage for Rachel Thomas. My ancestor Elizabeth Hughes' birth record listed her parents as Rachel Thomas and John Hughes. Birth of Rachel and John Hughes' oldest son was 1856. There is a 22 Nov 1854 marriage of Rachel Thomas to John Hughes in Llangwynwyd, listing Rachel as a minor. I don't know age of majority in the 1850s. Her father John Thomas as a laborer, which is consistent with 1841 census listing John Thomas with Rachel as daughter in his household with same occupation.
I was wondering, if this 1854 marriage record is correct, how Rachel Thomas from Llangyfelach, ended up living in Llangynwyd as a minor and then marrying there if her family was in Llangyfelach.? If the 1841 census is correct, she would be 18 in 1854.
I know people did not keep exact track of their birth years at this time. The marriage record says she resided Craig-y-bedw cottages, Llani Higher. Her father is listed as John Thomas on the marriage record, occupation laborer.
Interestingly, osprey pointed out possible marriage of older sister Mary 1852 in Llangyfelach to Calep/b Jenkins of the parish of Llangynwyd. Maybe there were connections between these locales for the THomas family.?
Any suggestions or help welcomed! Thanks.
