Hi jean,
No I don`t have any certificates for him,He actually shows up on my great grandfather John Brownrig`s marriage certificate as father of John Brownrigg.
Haven't got the date of John Brownrig`s wedding at hand but think it was around 1867.
Thomas Dent Fothergill`s occupation was down as it looks like Statesman,but could be stylesman.
What is weird is that he doesn't show up on John Brownriggs Birth certificate 1839,so I assume John was his illegitimate son,as john`s mother is down as Margaret Brownrigg. They were from morland,Westmorland.
I know Margaret Brownrigg was born around 1818 in Morland,so maybe this Thomas Dent Fothergill was around that era,but then again he could have been older,I mean it wasn`t unheard of for girls to get pregnant to the masters they worked for was it,just another theory

.
I wonder if anyone has access to the baptism records of Morland church,would love to know if Thomas Fothergill is mentioned on John`s Baptism records.
Best Regards
Coreen
