Margaret's maiden name is what I am trying to find. Where did you find the birthdates for Julia & Matthew? Those dates look about right according to the 1870 & 1880 US Census. The 1870 census says their ages as 17 & 16 but the 1880 says 26 & 24. The census seems to have a lot of discrepancies. Jerome could very well be short for Jeremiah but on both census he used Jerome and Jerome P. Margaret was used in 1880 census and Mary was used in the 1870. In the 1850 census it shows a Jerome Murphy living in Burlington, Middlesex County, MA. Since their first 2 children were born in MA I would assume that they would have been married in MA as well. What were the marriages you located for Jeremiah from 1850-55? Did any have the middle intial showing as P? Thanks for your help.
