Hi. Not sure if this is part of my family that I'm tracing, Gallocher from N Ireland (County Tyrone) who came to Kirkkudbright. One was Francis Gallocher born 1826 died 1881. His father was Patrick Gallocher, a crofter from County Tyrone, married to Bridget (maiden name unknown). Patrick's grandson was my ancestor born 1845 died 1922 and he moved to Walker in the north east of England, changing his surname to Gallagher. I have a lot of info on the Gallocher family in Kirkcudbright.
All the best
