Laura,
I read your email today - I have been out of the loop for years. Colin Cunynghame is my Uncle - my father is Harold Wallace Cunynghame (retired Butcher - born 1927). I new Roger in our youth however we lost touch with Colin and his family (sadly). If you would like to contact me I will do all I can to help fill in the gaps.
Kind regards,
Graeme Cunynghame
