Still Searching My O'Brien Family & Murphy Family

I have been trying to learn more about my O'Brien & Murphy families.

I think that Patrick Brien may have lived in the Glanworth area (Griffiths Valuation) before he married Ellen Murphy in Glanworth RC Parish, Sept 1851.   Both Patrick & Ellen are believed to have been born between 1820 - 1830.  Their first 4 children (Mary, Catherine, Elizabeth, & Daniel) were born/bapt  in the Fermoy Union Workhouse.  Two more children ( Ellen T. & John J) were bapt in the Glanworth RC Parish.  Much of this info came from the Mallow Heritage Center.  I do know that 4 of the children (Catherine, Daniel, Ellen T. & John J & their mother Ellen) immigrated to the Boston USA area in late 1700s & early 1880s.  All surnames were listed as Brien.   John J O'Brien is my direct ancestor.  Though I have information about those children who settled in the Boston area, I have no information about Mary or Elizabeth.

While in Cambridge Massachusetts, Ellen Murphy O'Brien's records indicate that she was a widow.  Her partents (John Murphy & Catherine Roach) were listed on her death record.  Patrick is believed to have died 1870-1880, in Ireland. 

Years ago while visiting the Fermoy/Glanworth area I read a book "A Glimpse of Grange" by Christy Roche.  In that book were 3 children Daniel Brien, Ellen Brien, & John Brien attending the Grange National School in 1870. Their Homeland Address was listed as Ballyhenden & Parent/Guardian listed as Labourer.

It would be wonderful to learn more about the lives of Patrick, Ellen, & the children Mary & Elizabeth, as well as any other ancestors I may not know about.

Thank You for your help,  Janet
