Does anyone have any info on the family of a William Aitken born in 1770's or very early 1780's whose wife was Helen Somerville? I have found names of 3 daughters for them so far: Elizabeth born Aug. 24, 1805, Margaret born April 30, 1808 and Isobel born July 14, 1809, all at Carnwath.

Margaret Aitken married Andrew Davidson on July 4, 1834 at Carnwath and it is this specific family I am trying to find info on. I have searched for birth records for the children of Andrew and Margaret and come up empty although I know they had at least two sons and two daughters born at Ratho in Midlothian:

Alexander Davidson born about 1836, married a Martha (possible maiden name Edmond), had at least two daughters Elizabeth and Margaret, and lived at one time at Newcastle On Tyne in England, was living at Westgate, Northumberland, England in year 1861

Helen Davidson born about 1838, married John Mitchell who was dead before April 1871, at least 3 daughters: Margaret, Elizabeth and Helen Mitchell; was living at Glasgow, Lanarkshire in year 1881 with 2 daughters and her widowed father Andrew Davidson

Margaret Davidson born about 1840, no further info yet on her

William Davidson born about 1842 at Ratho, got married in 1864 in London, England to Elizabeth Marshall who was from Saint Vigeans, Angus; eight known children: seven sons and one daughter; William and family lived at Ratho in 1871 but by 1881 had moved to Glasgow in Lanarkshire. I don't have a date of death for him yet.

Any info on this Aitken or Davidson family greatly appreciated-

Thanks from Nora
