Thank you for that. I did obtain a copy death cert entry for a Joseph Wray in 1908, but it wasn't the correct one so I'll check and if the info you have given is different to the reference I had, I'll get that copy cert. I use Family Search.org as well as other sites to pinpoint information and then I try and check that info out so that when I apply for copy certs I'm not wasting too much money if I find I've chased down the wrong person and especially check all different spellings etc.. I've been lucky up to now, though breaking the Wray/Kincaid side was a challenge. My mum's side has been the opposite and I've got reams on her branches. I'm now getting there though with my Irish relatives.
It may be that Rebecca remarried though no-one in the family can clarify and I've not found a marriage. I don't think there was a fall out as none of the family remembers hearing about a rift within the Wray side.
Thank you very for your help.
All the best
