Hiya again
went back to familysearch
Mary Runciman christened 31st march 1751 an EXTRACTED record....fathers name JOHN RUNCIMAN in Abernyte PERTH, Scotland
23rd March 1746 John Runciman married Elspeth Petrie in Inchture, PERTH, Scotland...the ONLY John Runciman marriage in Perth on record on familysearch within 10 years of Mary Runcimans christening
.......
so I think you need to see if you can find any more Runciman christenings from 1846 to 1851 in either Inchture or Abernyte....IF the parents are John /Elspeth you can then try and make the connection to John b 1858 and Mary b 1851
allan

NO CHRISTENINGS IN INCHTURE FOR JOHN RUNCIMAN 1745 TO 1765.....BUT
JOHN RUNCIMAN MARRIED SUSAN DONALDSON 2ND FEBRUARY 1786 IN INCHTURE,PERTH
I would think this MAY be your John Runciman b 1758(but this would make him 28 when he got married)
anyway.....there`s quite a bit of family info for you to research....should keep you busy, but at least you know there is quite a bit more Runciman family in Abernyte than you thought....GOOD LUCK........let us know how you get on....allan
