William Horsburgh (1632-1682) married it appears twice to Margaret Horsburgh and to Christian Horsburgh. They are listed as having seven children - all shown as being offspring of Christian. But that doesn't seem possible as Margaret died in
1674 and William in 1682, so Christian is unlikely to have had 7 children in 8 years so I think some of those children must have been children of Margaret? The only child with an identified birth is Thomas Horsburgh- born 1677 who would thus be Christian's first child after her marriage to William in 1676.
