Isaac Nichols born Birmingham 1800-1805

[sbunter]

Please can anyone help with locating my ancetors, the parents of this man Isaac Nichols (born 1800-1805) who was in Rochdale, Lancashire by 1829.
He first (possibly previous marriage as his status was not recorded) married 1830, no clues there.
Second marriage 1850 states father to be Isaac Nicholes nail maker
Third marriage 1859 no father stated.

I suspect that he was illegitimate and his grandfather was likely Isaac.
He always states Birmingham as his place of birth, the age varies a little, and he was in the metal trades - mechanic/boiler maker.
The spelling of his surname also varies a lot as he was illiterate.

This has been a brick wall for many years, and would love to find his ancestors,
thanks for any help,
cheers,
