Hi Nicky,
Sometimes I think the name of John Redpath must be the most common name ever! Makes searching it tricky. Since the post I made many years ago I've done further research and found out more. From what you say your John R was born at Branxton and was listed in Alnwick Workhouse in 1881 census. My John R was born at Milfield, Kirknewton and died at Longfield House, Marley Hill in Co. Durham whilst living with his son after his wife died. He and his wife have a gravestone at Warkworth Cemetery. They lived in that area in the 1890s.
It was his father John who was born at what I misread as Weldon House and set me off on the wrong trail! It was in fact Hetton House at Fowberry just a few miles from where I now live. Transcriptions have a lot to answer for!
I now have details of the latter Johns children, baptisms and places of birth plus the date of his marriage at Lowick to Isabel Graham but cannot get beyond that. Yes, he did have a son called John (the one born at Milfield about 1817) but he is definitely not yours as he never lived in Alnwick. He was a Farm Steward like his father.
Have you found a baptism for your John? That may give further clues. If I find any notes I've made in the past about the various John Redpaths I'll post on here again. Walter seems to have been a regular name in my line, more unusual than John, so if you discover any Walters we might be connected. You can find out the maiden name of your Johns wife, with a bit of intelligent deduction, if he married and had children, by checking GRO online birth indexes which save you buying certificates.
