Christopher and Hilton Watson had children in Staindrop from 1726 - 1746 before moving to London where they died. Fortunately the parish chest records give their ages: Christopher died in 1768 aged 76 (leaving a will) and 'Mrs Hilton Watson' died in 1770 aged 66, so born c1703/4.
He is probably the Christopher Watson born to another CW in 1693 in Staindrop, but I can't find either their marriage or her baptism, despite her very unusual name.
There are a few Hilton's born in the area (Tweddel 1693; Lawson 1703; Shaw 1712; Richardson 1712), but only one is of the right age and they are all listed as male. The one of the right age went on to be High Sheriff, so it's definitely not her.
I wondered whether her surname was Hilton and she just used that as a 'nickname' but perhaps ithers can spot her.
Thanks.
