Hi,
Fenton Thomas Lambert married (1) Mary Lambert, had daughter Mary. Married (2) Mary Halliwell. He always seemed to have one or more Marys with him! in 1851 He had his first wife Mary, her mother and their daughter (3 Marys) living with him. In 1871 his 2nd wife Mary and his daughter were with him. In his later years Thomas was Municipal Registrar of Birth and Deaths in Stainland, Yorks.
I haven't found anything about Thomas Lambert, other than that he was a tanner, married Mary Garlick in 1800. He seems to have died before 1841, as his Mary was living with her daughter and son-in-law then.
Have you checked out Malcolm Bulls site?
http://freepages.history.rootsweb.ancestry.com/~calderdalecompanion/l.html - well worth a look, quite a bit of Lambert info there, some of which I have provided, along with many other contributors.
Cheers,
Val
