Derrig's from Tourmakeady

My Great Grandfather Martin Derrig was born on 15 March 1884 in Tourmakeady, Co Mayo.  He arrived in Boston on Jun 1st 1905 and settled in Portland, Maine.  I know we still may have family over in the area including a relative by the name of Nora Derrig.  Hoping for perhaps more family information on where exactly he was from and to connect with relatives.  

 

Thanks.
