Yes, Shelah Charman (1705, Slinfold/Warnham) is in my file - he was the son of John Charman and Sarah (nee Stanford). The name is used a couple of generations later with a Shelah born in 1762 to Daniel Charman and Judith (nee Bennett). My computer tells me these two Shelahs were 3rd cousins, 3 times removed - a bit of a stretch for the naming conventions that people used, so maybe there was a closer cousin that carried the name.
I had a quick look at the use of the name Shelah (etc) in the parishes around Warnham where my ancestors came from (unfortunately I don't have the Slinfold PR but I do have a lot of the others (Horsham, Rusper, Rudgwick, Itchingfield, Billingshurst, etc). There is only one use of the name Shelah in those parishes in the period 1705-1762 - its Shelah Gibson baptised 28/4/1732 in Rudgwick, s/o Joseph. I'll have to have a closer look at him to see if I can find a link.
Outside of the Warnham area, theres Shelah Pratt in 1776 in South Bersted - he's the grandson of the 1705 Shelah Charman.
Then we come to Shelah Wales born 1792 in Rusper - who incidentally married Elizabeth Charman. This Shelah Wales is the son of Robert Wales and Sarah (nee Shaw). I couldn't see how that one occured, buty I did find a burial of Shelah Shaw in Charlwood in 1777 aged 74 so he may have been the grandfather of Sarah Shaw. Another one to check!
And thats about all there are in the Sussex/Surrey area where my ancestors lived - and there seem to be precious few elsewhere in the country.
It is biblical in origin, but not limited to Jewish families as far as I can tell. There are no particularly "biblical" names amongst Shelah Charman (1705)'s ancestors between about 1550 and 1705.
And thats about it for the name Shelah.
I have the Charman tree in Ancestry and GenesReunited. If you let me have your email address through a private message, I'll set you up as a guest in Ancestry.
