It's possible that your Ryans and Vicars are from Lackakera, Latteragh, Co. Tipperary. I have an Elizabeth Vicars in my line that was born abt. 1805. I have determined that she was probably from the Lackakera area as that seemed to be the only area that the name Vicars or Vickers can be found in Tipperary. She married a Thomas Kirwan abt. 1837 and I found one of the children's baptism records in Templederry which is nearby. On the Griffith's Eval, Thomas Kirwan is listed in Lackakera, Latteragh in 1850. THey emigrated to Newburgh NY in 1853. We were always told they were from the Thurles area which is nearby also. There is also a James Vickers in Lackakera on the Griffiths Eval. A good portion of the Irish Catholics in Newburgh at the time came from Tipperary and there were a few Ryan families. I would look in that area if I were you.
