Hi Sally,
I apologise for my slow response!!
Joseph Grubb was I think baptised at Leominster on 5th Jan 1834, the son of Joseph & Mary Grubb.
He married Anne Davies at Kinnersley, Herefordshire, on 23rd May 1853 I think.
They appear to have had 7 or 8 children.
The family appear to descend from Joseph and Elizabeth (nee Toy), married in 1767 at Martley Worcestershire.
I will investigate a bit further.
Regards and Best Wishes,
Joe.
