I looked for a baptism of a John Patterson in 1762 in Houghton le Spring anyway, just in case, but there wasn't one in that year and not only is that the first year in the records, but there's also a big gap afterwards with the next year available being 1770. So no joy there.
I can't yet narrow down where to search for Frances Briggs (John Patterson (b. 1785)'s wife) but that's the easily solvable dead end as I think she dies after 1847, thus in the era where deaths are registered. So if I get her death certificate that'll give an age and I can look for baptisms for her.
And I thought I'd look for Thomasin Wilson's baptism (Stephen Patterson (b. 1806)'s wife), in Walker, Northumberland in 1807ish, but there are only records available from the 1840s and 1850s for that parish :(
So apart from the initial glee of another generation in the Patterson line that was a little bit of a disappointing afternoon/evening's work. I'm a tad over-pessimistic on some of them actually - there are probably more records available in the actual parish records (and they may have more information in than the Bishops' Transcripts do). But for now they're not online so I've got to the end of what's easily accomplishable at home for those lines.
I should spend some time today getting the last couple of days evidence into the database etc, then decide what next. There's a couple of choices - blatt through the censuses for Stephen's sibs (I have probable marriages for 2 of them, and potential matches that I need to double check in the censuses). Or start looking for the baptism of Margaret Oxley who is the wife of the next generation down of Pattersons (so J's great-great-great-grandmother), but she seemed to either be unsure about her age or lied frequently as there's a 7 year range for her birthdate across the various censuses ;)
