As "Skoosh" says, just as it's spelled, with 'ai' not 'a'.
Seems half of Fife is descended from the "Fife Laings".
John Laing (1740-1805) & Margaret Greig (1746-1819) are my 5x Great Grandparents.
John Laing (1778-1848) & Ann Black (1775-1853) 4x.
Thomas Laing (1807-1872 & *Isabel(la) Edmund/Edmond/Ednie (1807-1870) 3x.
Isabella Laing (abt 1833-1911) & Alexander Wannan (1835-1918) 2x.
*Isabel Edmund, daughter of David Edmund & Isabel Hayne, was born 26th bap. 30th Aug.1807 at St Andrews, Fife. Isabel, her brother David & sisters, Agnes, Janet & Christian, all swap between the surnames Edmond & Ednie. (Great fun to track!)
Thomas Laing & Isabel Ednie married 1st Aug.1829 at Crail, Fife. ScotlandsPeople have wrongly transcribed Thomas' surname as Lainy (waiting for confirmation from SP that his surname is Laing). On the next page is the birth of John Laing, Son of Thomas Laing & Isabel Ednie, born 2nd, bap. 24th Oct.1829 at Crail. (Got the name right this time.) I've not found son John on any Census Returns etc. & he may be the John Laing who died 22nd July 1839 at Third Part, Kemback. Thomas Laing & Isabella Edna his Wife had a daughter baptized 1839 at Kemback.
