Looking for info about my Paternal Granddad and his parents and extended family. He was from County Antrim, born in early 1870's, Father's name was John, Robert married Mary Rennie in 1906 they had 2 children, Hugh and Margaret. Robert passed away in 1926 in Dervock, County Antrim. Any info about Robert's parents, place of birth, date of birth and siblings would be greatly appreciated. Thank you.
