Looking for family of Bryans/Boyle

Thomas Bryans born about 1845 married Margaret Boyle born about 1851 in the Church of Antrim, Northern Ireland.  They had 9 children, Annie, Willam, Robert, Mary, Andrew, Jeane, john, Thomas, and James. My grandfather is John.  I am looking for any children or grandchildren from these 9 kids.  My grandfather, John, came to America in about 1912.  I also know that James came to America.  I am hoping to find any relatives that remained in Ireland.  I believe several may have gone to Canada.  According to the 1911 census, Thomas and Margaret lived at 173 North East Division, Carrickfergus.  Any input regarding this family would be greatly appreciated.
