Hi Daval57 , I have only just seen your post , so may have missed the boat.
Have you been to Sighthill Cemetery?
I have several family members buried there - viz. 1855 - died 1 jan - aged 9 mths - Euphemia McColl Blair
1859 - died 7 Feb - aged 2 1/2 yrs - James Hislop
1860 - died 3 Nov - Euphemia Blair ( ms Campbell) - aged 29 yrs
I have no doubt there would be other Hislop family members buried there but have no details at this time. As I live in Australia , it is unlikely that I could go to look for myself , so I shall wait to hear from you,
Regards, Thommoje
