Glenda, it looks as if these are very blended families from whatever angle you look. But I see that Mary wasn't Irish. Angus seems to have some sons already (born in Ireland) and maybe James and Matthew Lang were Mary's by a previous marriage. It is hard to tell on the 1841. I suppose Cursty could be someone's interpretation of Judy if not written very clearly. Piece: SCT1841/565 Place: Houston & Killellan -Renfrewshire Enumeration District: 3 Civil Parish: Houston & Killellan Ecclesiastical Parish, Village or Island: - Folio: 3 Page: 10 Address: Crosslee LONGMUIR Charles M 30 Coal Miner Ireland LONGMUIR Juidy F 25 Ireland LONGMUIR Elisabeth F 1 Ireland It certainly looks as if this is the same Elisabeth as the 11 year old in 1851. But I can't make sense of it all. Where did you get the certainty that a Judy Paterson married Charles Longmuir? Of course they may just have lived together and changed names? Who was Angus married to earlier? Do you have sources for the original information? Cheers, Mary
