Hi All,
My apologies for the confusions I may have added - I was working across 2 pc's and keyboards and excited about maybe tracking down some info about these lost years. I have done all my research from Scottish records as these are the only 3 English records I have after 10 years researching.
My info comes from census or what is recorded in the Scottish records, so as we all know, census information is only as accurate as the person giving, and the person receiving, and the person reading the records.
I'm at work so will need to piece all this together at the weekend, but I have Isaac's death certificate, so that's where I got his birth date.
I didn't know there was a freeBMD for Sunderland, thanks for that pointer, but then I've only recently been able to narrow England down to Sunderland. A son turns up later in Northumberland, went to the mines for work.
My research has thrown up plenty of anomolies for this family & there's probably an earlier Hugh who died and was "replaced" by my Hugh a few years later.
I'll check what info I have for them for 1891 - this is really helpful all, even if it throws up more questions

This family was big and mostly on the poverty line so education and being nice to the authorities ( ie census takers) probably wasn't high on their list of priorities, and that carried on for a couple more generations.
Cranston I can't comment on, I was hoping for local knowledge. I got Remote or Rimote from original documents, I'll re look at them, but that's what I read & with a few years of practice, I'm not often too far out on turning chicken scrawl into words, but as I say, this part of the world is a complete unknown to me, so I am flying blind.
If you can bear with me I'll retrace all of my info for these three over the weekend and get back to you all.
Thanks for your efforts, it's great to get a step forward.
Cheers
