As far as I know there isn't but there are children of William and Sarah that I'm not sure exactly where they ended up. Certainly my direct line through their 3rd youngest child Henry has no connections to Smiths. This couple had 9 children beginning in 1815 with the last being born in 1838. They did have a Thomas born in 1824 and he married Martha Colley and lived in Trysull Staffordshire and I can't say definitively but I don't think there is a Smith connection there. I haven't found what happened to their second daughter Elizabeth(1817) nor their son John(1827). Their daughter Jane(1834) had an illegitimate daughter Harriet in 1857 and after the 1861 census disappears. Perhaps the death in Wellington in 1865 is hers. What happened to Harriet ??.
There are definite unknowns in this family but so far I'm not aware of any Smith connections. Not all of the children remained in the Wellington area. Ann and William definitely remained there with the parents but Henry ended up in Shrewsbury, Sarah in Liverpool, Thomas in Trysull, Benjamin in Dresden, and Elizabeth, John and Jane unaccounted for.
I'll make a note and if I ever come across a Smith connection I will revisit this post and contact you. What was you Ggrandmother's name?
