Hal, There were McNamara in the area < 1850. Alexander McNamara married Anne Clarke on Jan. 7, 1848. On that same day F. Donahoe married Ellen Dooley. Either Fr. Gibson or (more likely) the co-pastor at St John's (Worcester), Fr Boyce officiated. On April 8, 1849 James McNamara married Bridget Doe (same Church). This was just after Lent so there was a number of marriages on that date: John Cummins to Catherine Flemming; James O'Brien to Anne Smith; Jerry Wilalhm to Sophia Fey or Fay. I have looked for McNamara children being born to James in Worcester in the years that followed their union & found none. I don't think this couple resided in Worcester, perhaps Westboro? Female McNamara's married by the Catholic Church (Fr. Gibson @ St. John's) <1850 in the area are. 4/21/1845 Michael Canarey to Margret McNamara (no others that day) and on 6/8/1849 Edmund Barnet to Mary McNamara (no others that day). Let us know if this helps, John
