I'm looking for information on Thomas Lang b. 19 Jul 1861 in Sprouston, Roxburghshire, Scotland. He moved to Londonderry and married Mary Ann McElroy from Bushmill, Antrim in 1885. He was a partner in Kerr, Lang and Jackson, seed merchants and implement agents on the Strand in Londonderry and lived with his family in Londonderry as late as 1912 (signed the Ulster Covenant with address 79A Foyle Rd). His wife and four of her children were buried in the City Cemetery in Londonderry but he is not buried there. There has been some suggestion that he may have left Mary Ann for another woman, but this is unconfirmed. I have no idea whether he left Ireland or lived out his remaining days there.
