In 1844, James was a Widower when he married Alice Mather. Both were of fulll age. The same year another James Brooks married Sarah Mather.
His first wife probably died about 1841, and after a suitable time found a new younger partner, Alice Mather. She would have already been 6 or 7 months pregnant with George when they married on 6-Oct-1844.
Can't find him on 1841 census, so unable to match his first wife and family with son John (b.1835).
In 1849 James Brookes was a witness at the wedding between Samuel Mather (his brother-in-law, Ann's brother) and Ann Nightingdale.
