My dear Mum died a few days ago. It was expected as she had been in hospital for a while. I have informed all the relatives that I know of (although they are getting fewer and fewer as DM was 87). However, in DMs house was a Christmas card from someone who I don't know but whom I believe to be a cousin of my mothers. The card still has the envelope with it with an address sticker on - the person lives in the USA. The card is also addressed to my DF who died over 2 years ago but clearly this person doesn't know that (sh'es not related to Dad).
I obviously need to write to this person and let them know that both my parents are now deceased but I don't know what to say. A one liner in a card saying something along the lines of "just t o let you know that DF and DM passed away on XX" seems a little brief, but I have no idea how much this cousin knows about my Mum and her family. I don't think there has been any contact except for Christmas cards for a very long time. So do I just go with being brief or do I write a bit about Mum's family who have been left behind. I'm assuming this cousin in in her late 70's possibly 80's.
