Thomas Ryan & Bridget Mackey Ryan

Hello Again Ireland Reaching Out,

Last summer you were of tremendous help when I asked about my Casey and Ryan relatives in Turagh! So I'm hoping you can help again. I've been looking at Griffith's Valuation and see that in 1851 there was a Thomas Ryan (Stephen) and a Thomas Ryan (Luke) residing in Turagh, as well as a Bridget Ryan. The map reference for Thomas Ryan (Stephen) is 28 34; for Thomas Ryan (Luke) is 28 107; and for Bridget Ryan it is 28 66. I've been trying to figure out which Thomas Ryan is my grt-grandfather. Could you explain the "Luke" and "Stephen" references? I'm unaware of any Luke Ryan or Stephen Ryan in my family; there are, however, an abundance of Williams, Michaels, Thomases, and Johns! 

In January 1917 my grt-uncle Thomas Casey died in San Francisco. My grt-grandmother, Hanora Ryan (dtr of Thomas & Bridget), was the informant listed on his death certificate. At that time she gave her maiden name as Hanorah Ryan Stephens. This has puzzled me for a very long time. But now I'm wondering if the "Stephens" can be tied back to the Thomas Ryan (Stephen) of the Valuation? 

I look forward to hearing from you! Thanks ever so much!
