Congratulations to everyone on this thread!
There were some mind-blowing discoveries.
I just sat back, commented, didn't do any worthwhile lookups, and then leapt in at the end!
When I read the thread again this morning (my time) three things jumped out at me:
a) CatOne's incredible find of the family (with Uncle Elihu PEARSON) under ELICSANDER in 1881
b) CatOne's post of Uncle Elihu in 1871 showing his birthplace as Keswick (that Keswick birthplace for Elizabeth in 1861, 1871 and 1891 had niggled at me - as I once mentioned)
But I feel that I still wouldn't have twigged without:
c) Gallium's mention of the 1858 marriage of a William ALEXANDER & an Elizabeth PEARSON - that was what made the light go on!
However, I'm now wondering whether we do have the correct family for Elizabeth PEARSON ...
Elizabeth PEARSON bap 1830, parents Thomas PEARSON & Mary (probably LANCASTER), Crosthwaite probably is the right one - and date is perfect for 1871 and 1891 censuses, and 1893 death.
But ...
There is another possible Elizabeth PEARSON just a couple of years earlier - Elizabeth PEARSON bap 1829, parents Joseph PEARSON & Anne, Crosthwaite.
Same parents had (also Crosthwaite) John bap 1827 and Joseph bap 1831.
Those parents might well be Joseph PEARSON and Ann VICKERS, marriage, 3 Aug 1826, Crosthwaite.
