Wow, thanks everyone for the input. I have found all of the info you have posted already and a bit more to go with it. I didn't know about the statistics summary so thanks so much for that. I have followed a lineal data path and gotten myself to some dead ends so am now trying to flesh it all out.
George, William and Jane are all siblings, born of Patrick Young and Hannah Fletcher, Patrick's second wife. His first, France's Boles, died after giving birth to their daughter In 1865. Two girls from that marriage, Frances and Mary. George, b. 1874 is the George that came over to Canada with my gg Robert. When I carefully read through everything there are some neat tidbits mentioned.
1834. Patrick b. 1816-ish, Henery b. around 1807 and James who may have been born around 1812 are all on Griffiths in Cadda. I don't know when but Henery moved to Garvagh and married Jane Hamilton in 1848. They had at least two boys, Edward b.1866 and James b.1849 and most likely more. I believe they also had a daughter Margaret who was married in 1892 in Garvagh and witnessed by Jane Young. I have yet to get a birth record for Margaret. Edward died at a young age in 1881 as reported by his brother James. Jane died June 6,1888 and Henry died four days later as reported by son James. James had a really rough week. When James died in Caddagh Glebe in 1922, his cousin Jane Young was present at death.
So, I think that Henry and Patrick are definitely connected and am filling out both family lines as well as connecting them together. The common thread in all of this is Caddagh Glebe. Now that I know how small a community it was, I am more convinced that their are family connections among the Youngs there. Somehow Robert fits into it all.
