Mary Glynn O'Connor, age 57 (born c. 1838 in Ireland to Michael Glynn and Julia Crowley) died in Cambridge, Massachusetts, on 27 Nov. 1895, of burning. She was the widow of John O'Connor (Family Search data). On the Roots Ireland (paid search) website, there is a record of a Mary Glynn born on 20 Nov 1838 to Michael Glynn and "Judith" Crowley of Taughmon, Westmeath. Sponsors were James Merlehan and Peggy Mulligan.
Also from Roots Ireland: John Glyn born 18 Dec 1835 to Michael Glyn and Judith Crowley of Taughmon. Sponsors Patrick Crowly and Mary Merlerhan. Bridget Glynn b. 20 Jun 1841 to Michael Glinn and Judith Crowley of Taughmon. Sponsors Andrew Murphy and Marcella Keogh. Marcella Glynn b. 10 Mar 1844 to Michael Glynn and Judith Crowley of Taughmon. Sponsors Simon Lovely and Judith Murphy. Julia Glynn b. 11 Jan 1848 to Michael Glynn and Julia Crowly of Taughmon. Sponsors Thomas Fagan and Mary Daly. Could Judith and Julia Crowley be the same person, or would there be two Crowleys married to Michael Glynns in the same townland?
I found this material because I know that my great-grandfather James Henry Glynn was born in County Westmeath around 1854-1858 (in the month of September) and that his parents' names were Michael and Julia (I don't know his mother's last name). I am still searching for his specific origins. He immigrated to Waltham, Massachusetts, between 1871 and 1873 and then settled in Cambridge, Mass., and married Ellen M. Carr. If anyone has information about him, I would greatly appreciate it.
