I think this is the family I'm looking for but very confused how can bethania marry William Gray in 1822 her first husband then marry James aka mobbs in 1815 / 1816 ? And have a son to William born in 1822 7 or 8 years after she married James ?
Firstly, I've not found proof of an official marriage between William Gray and Bethania Smith, when I said "married" I meant in Romany liaison terms - lots of Romanies were never "legally" married in those days. Also, it wasn't uncommon for them to have more than one partner at the same time... So that solves that question.
Williams "usual" wife was Bethanias sister, Tabitha Smith.
Bethania seems to have James Mobbs as her "usual" partner.
With him she had: Eldri/Eldorai Gray who married Moses Smith,
Joshua who married Harriet,
Righteous who married Sage/Sagey Heron,
Cornelius, (apparently unmarried)
Francis who married Selina
Letitica,
and Moses who married Silvia Smith.
