Your Alexander Kinghorn was born to Alexander Kinghorn & Mary Thomson [maiden name Home ] Mary was previously married to Robert Thomson whom she had 2 children Margaret& Robert.Mary was born 18 Feb . 1845 @ Chirnside , Berwick & the daughter of John Home & Margaret Cockburn. Alexander Kinghorn Snr was born 10 Sept 1845 in Ednam , Roxburgh to John Kinghorn & Isabella Frater .[Alexander was a twin ] John & Isabella also had another set of twins . I have further information on this family if you would like it .John Kinghorn was born 26 May 1811 at Ednam , Roxburgh to Alexander Kinghorn & Jane Buccham. I looked at this family to see if it linked up with mine - it could well do but it would be very earlyback in the mid 1700's as my Kinghorn family lived in Eccles , Berwickshire , this is as far back as I have got. Happy hunting!
