And I've found a couple more a bit like this. There is a question along these lines (re Edward Crowe) on the Wiki but it does not have an answer!
If a notice just talks about "the heirs of" someone but mentions no names apart from the deceased, I am presuming we don't key anything? We can't mark the deceased as "Self" and we don't know his/her relationship to any possible heirs unless that is set out as in the first record I posted in this thread...
