I can't seem to find any connection at all. I can't find a baptism for Thomas in Rothbury nor a marriage anywhere for Joseph Embleton to an Elizabeth.
They are in the 1851 Census HO107/2423/F129/p18 with John Ramsay as a lodger but no sign of Thomas.
1871 RG10 5194/F44/p7 Elizabeth has died, John Ramsey is a lodger and Thomas, 44, is a servant along with Mary Ramsay,26 and Thomas Ramsey, 20.
1881 RG11/5138/F5/p3 Thomas is now his son again and is married with children
All theses Census entries are on fs.
