CelticAnnie,
in 1871 your Thomas is a footman for Henry Hawkins, Magistrate of the County of Monmouth and landowner, living at 22 Moorfield Place, leominster, hereford
Go back 10 years, he is 14, is at Llysworney (listed reg dist Cowbridge) and is an under gardener for what looks like R Cook Carne Esq, sorry i can't read the address but he is a barrister, proprieter, magistrate not in practice, landed - the handwriting on this one is awful - perhaps some kind soul on here could look at it and make something else out for you
in 1851 he is with dad John and mum Ann in West Street, Llantwit Major, John is a Farm Labourer
Glad to be of help
