Hello
I am interested in the links between the Dunnings of Wolstanton and the Dunnings of Wellington. I have the Thomas you are talking about as the son of Joseph Dunning and Grace Porter bp Wellington 3 May 1795 but I may be wrong.
I have this relationship as a vague possibility. The problem is that I believe Joseph Dunning married Grace Porter on 5 August 1803 at Wellington All Saints according to two secondary sources. Since Thomas married Alice Onions on 24 July 1815, I believe he was born in or before 1795 your quoted date for his baptism is quite reasonable. Could I ask where you got this date from, please.
I must admit I haven't been researching this part of my family tree for some time and, having a quick look through them, realise my Dunning notes are badly out of date. I note, however, that a Joseph Dunning was buried 7 January 1816, aged 44, in Lawley Bank (south of Wellington, Shropshire) and that a Grace Dunning can be found in the 1821, 1841 and 1851 censuses as a widow.
I am also interested in James Dunning who married Rebecca Tunks in Wellington in 1730 and John Dunning who married Martha Lane in Wellington in 1722. Interestingly two brothers of about the same age and with the same names were baptised in Wolstanton in 1705 and 1703, the sons of Joseph and Maria Dunning. There are no marriages in Wolstanton which would be likely and no baptisms in Wellington at about the right time either - it is very tempting to tie up the baptisms in Wolstanton with the weddings in Wellington but is it right?
It would be certainly correct to note that the possibility exists. More research is needed (

) Why did the brothers move the Wellington? Work? As an aside, I have a reference to a Joseph Dunning marrying a Mary Baslow (or Barlow) in Wolstanton on 1 February 1701 according to the IGI, if this helps.
I've never tried to connect the Dunnings of Wolstanton and the Dunnings of Wellington but it does seem to be an avenue worth travelling down.
