Hi again, You say there are a number of children born to a Robert Thompson and a Mary Johnstone one of which is in Carrickfergus. I have trawled the LDS site and dont seem to see any of his children. One is Robert my G Grandfather and there were 5 others, Samuel, James, Ellen, Agnes and James.Unless I am looking them up the wrong way. Carrickfergus is probably the right area as on the copy of Roberts Baptisimal certificate it says Silverstream which I believe is the same area.I'll keep hunting!!
