Thomas Brown of St Helens Auckland

[0191alex11]

Hi!
    Can anyone help with the following?

I have a Thomas Brown born and baptised in 1799 at St Helens Auckland, son of Charles Brown and Grace Gibson.
He married a lady called Mary (born circa 1805) and had the following issue:

Grace 1826, Thomas 1828, Jane 1831, Elizabeth 1833, Charles 1835, George 1837 and John 1840.

Cant find a marriage for Thomas and Mary, and the only census I can find is the 1841 for Evenwood and Barony, where he is living (his brother Charles born 1797 is living there also with his family).

Any help much appreciated!
