Robert Charles Shiels was baptised 1859 at Churchtown Presbyterian Church and seems to have added Price to his name. I found his brother Samuel after I discovered Samuel named a son Robert Charles. Samuel's marriage record was interesting as it listed his residence as Seygorry (named after St. Guaire), his father as a ploughman (a more skilled job than 'labourer') and Margaret Anderson was a witness (she also lived in Seygorry and was connected to my grandfather's family).
An 1855 Scottish birth certificate is a goldmine of information so let us know if you are having trouble deciphering it all.
