Good Evening Morag,
I am the great grandson of John Crum who emigrated to N.Z.circa 1875.
Although not being involved in the 'family tree' history gathering, my sister has researched extensively the Crum family
and has a wondeful collection of info and photos I am sure she would be prepared to share.
If I am able to assist please contact me on the email address forwarded herewith,
Regards,
Roy
