Hi Vanessa
I'd like to echo Paul's welcome to RootsChat! You should find it a really useful site

I'm not very familiar with the area of Dorset you mention, so I may not have got all the relevant entries, but here goes -
Arnold, Edward, 1824 Oct Sturminster Newton , A, servant bachelor, first grant July 1819
Snook, Edith 1823 Dec Manston, W 714, Widow
Snook, Henry, 1826 Feb Hazelbury Bryan, W 166 Yeoman
Snook, James, 1839 Mar Stour Provost, W 186 Gentleman
Snook, Jane, 1855 May Stour Provost, W 452 Spinster
Wareham, Robert, 1851 Feb Stourpaine, W 169 Bricklayer
There are several more Arnolds in Puddletown, Poole and Yetminster
The only Dennises were Wyke Regis and Weymouth
Lots of Hardys all over the place but not, I think, your valley
Pikes in Canford Magna, Bridport and Church Knowle
The only Wolfry or similar were around Poole.
Hope there may be something of interest amongst these but please do come back to us if there are specific people, dates or villages of interest so we can double check.
Best wishes
Angela
