Mossops of Borrisokane

Hello, I'm researching my 2x great grandmother's family. Her name is Susan Jane Mossop, b. 12 Dec 1839. She married William Henry McComb(s) (1838-1911) on in 15 Dec 1862 in the Corbally Parish Church, County Tipperary. They had one daughter, Annie Elizabeth, b. 9 Oct 1863, prior to leaving for America in Sept 1864. Susan's death certificate says her parents were Jonathan Mossop and Helen Martin, both born in Ireland. I am not able to find records for them in Roscrea or Corbally. I have found two people who may be Susan's parents in Borrisokane. My theory is that Susan might have been born and reared in Borrisokane. I find a Jonathan Mossop and an Ellen Mossop living in Borrisokane on the Griffiths valuation records for 1852: Jonathan Mossop in Liskinlahan, place type "townland" and Ellen Mossop in Rathmore/Tower Hill, place type 'other'. I'm looking for information on these people, especially birth/baptism information for Annie Elizabeth McCombs. Can anyone help? Thank you!  Liz.....I can be reached at this email: lizparks47@hotmail.com
