James Ai(t)kenhead and Ann Fleming were married in East Kilbride in 1743.
Their recorded children are
Janet, 1757
William, 1760
Ann. 1762
Jean, 1766
all born at Headhouse, East Kilbride.
That looks like a very long gap between marriage and first child.
However there are three baptisms in Blantyre, father James Aikenhead, no mother listed
Alexander, 1744
John, 1746
James, 1752
all born at Park. I take this to be Blantyre Park.
I am wondering if these are earlier children of James A and Ann Fleming.
Can anyone think of a way to confirm this? There are no relevant wills or sasines.
