Hi Randh
I have looked on the I.G.I for a marriage there is one but wrong wife and no info. Apart from the 1841 You don't say if you have the family on any census or not.So i had a look in the Manchester Directory 1850,there are 7 Males but no Thomas.However there is Female Sarah Coffee Widow 1 Haybrook Street Norton Street.Thought i would mention it.
