Peter McGuirl b. 1847

Searching for information on the descendents and/or ancestors of Peter McGuirl b. 1847 in County Leitrim, Ireland- married Mary Pryor b. 1851 in Leitrim.They had 6 children, most of whom immigrated to the US in the late 1800's.I only know about my direct ancestor Thomas Francis McGuirl b. March 14 1873 in Leitrim, came to Prov. RI abt 1892, and married Catherine Donovan b. 1875 in Cork; m. 1898 in Prov., RI. Looking for names and descendents of these 5 siblings of Thomas Francis. I believe that Peter McGuirl also had a 2nd wife with whom he had 6 more children.Most came to the US, some stayed in Ireland.Looking for their names. Also wondering if Peter came to the US or not and his death date.
