Reilly's of Shankill, Antrim

I have been researching some family history, and we are planning a family trip to Belfast this September.  I have been researching many sites, and have accumulated a lot of information.  However, it seems I've come to a standstill.  We would love to connect with any living relatives still in the area, but I am unable to find any more information. My great-grandma Sarah  Reilly was Baptized in the Church of Holy Cross, Ardoyne, Belfast on the 17th of January 1892,  immigrated to Canada in 1912 by herself, and married Sam Fonger in 1924.  I believe her parents names were Thomas Reilly and Mary Ann (Campbell) Reilly.  They had 6 children: Ellen Jane, Thomas Henry, Corneilius, Mary Ann (maybe went by Margaret, or Molly?), Sarah Ita Josephine, & John.  Thomas and many of the children worked in a spinning mill, but I'm not sure which one. One of the sons immigrated to the US, but I'm not sure which one either.  One of the girls married a Jacob Moore, we believe, who may have been in the military.  I believe they had two girls, Maureen (Mollie?)  Moore (a nun), and Joshephine Moore. I found a census in 1911, where Margaret Reilly lived on Leopold Street in Shankill, Antrim, with her grandmother Maragaret Campbell, and a Thomas McGarry.   We would love to learn anymore information about the family, where they are buried, and any information on Sarah's siblings, and if there are any living relatives in the area. I have attached the only pictures my Grandma has of the family. My Grandma, Sarah Reilly's daughter, is still living, and would love to know any information she could! Thanks
