I am hoping a John Ferriter/Feriter/Faritor can be found in the census for Boston in 1840. one daughter over 10, one son under 10 and possibly 2 daughter under 10 (one for sure). He was born about 1811 so was around 29 years of age and his wife was between 30-40 years. They were born in Ireland. The fourth children, a girl, was born about 1840 or 1841 in Boston. Thank you very much. Audrey
