There were also cards for the deaths of other members of the family (Memorial cards). These also intrigued me, especially as three of them were for my grandfather's mum, dad and brother and were all within a few days of one another. They all died of cholera in India, and my grandad was a young boy and was sent back to the UK under the ward of a returning family unknown to him. He was adopted by his grandfather and aunt, who brought him up on his return.
I have been dipping into my family history for a few years, started some collaboration with distant cousins (geographically and biologically) and have now reached a stage where I realise all I have been really doing is collecting ancestors on my family tree.
