Hi charlie07,
Thanks for your reply. I know Karen (a step-in-law relative, though we have never met) and we correspond regularly. I also know Agnes (Karen's cousin and your Grandfather's step-sister) very well and we keep in touch, in fact she phoned me yesterday afternoon and we had a catch-up chat. She will be turning 89 next month. And yes, both Agnes and I are in Australia - different States though.
My 'relationship' with Agnes is really through my in-law side of the family - all from Scotland. My late mother-in-law's (Rebecca MacAndrew - 1st husband John Ritchie) second husband was Leonard Montgomery Stark who was previously married to Isabella Naismith Morrison (5th born of the 7 Morrison girls). She was sister to Evelyn Morrison who was married to Andrew Elder - your Grandfather. I know, it's all very confusing!!
