A Niven Agnew (died 11/2/1799) married Elizabeth McCrea
(died 11/8/1848, aged 91 at Balscalloch, Kirkcolm Parish).
Believe this same Niven lived in Leswalt (neighbouring Parish to Kirkcolm) at one time.
There is a Norma Agnew, Po Box 371, Mt Omnaney, Brisbane 4074, Queensland, Australia who
may be connected.
Hope this leads to more information
