Can anyone help me with this family? There is a huge discrepancy in age of Jon and Bridget between 1880 and 1900; however, because of the listed children it has to be the correct couple in both cases. Thank you for any help you can offer. 1880 census North Brookfield, Worcester MA John Mahoney 54 b. abt 1826 ireland farmer (looks like John 2nd) Bridget (Nova Scotia) 51 Ireland keeping house abt. 1829 Kate A. 20 school teacher James H. 18 at school Nellie N or M. 15 at school Michael Mahoney 22 boarder, farm laborer 1900 census N Brookfield Worcester MA John b.
