hi, did you find the info you needed? i looked for you but could only see one who would fit your thomas. in the 1871 cencus there is one thomas harvey aged 40. (the other two in there are 42 and 43). but this states he was born in felstead, as i dont know essex im not sure if its close to brentwood. i do have the 1841 essex cencus as some of mine i found migrated to there, so if you still need the info ill gladly go through the discs for you. couldnt find amelia , she would prob have been married by 1871 cencus. let me know if you want me to do a search, jenny
