My Gt-aunt, Sarah Muirhead (1854-1926) married Charles Boyle (1841-1908). They lived most of their lives in Racavan parish, County Antrim. However, for a short period (about 1871-1874) they lived in Pennsylvania where two children were born; Frances in 1872 and Charles Andrew in 1874. This information came from a grandson of Charles Andrew, and this was the extent of his knowledge on the subject. I would welcome any advice or suggestions as to how I might track down these two births in unknown locations in PA. Thank you. From John Muirhead
