Isn't it wonderful...

... that when someone shows you how to re-interpret a mystery that all the records you couldn't find are now easily found!

Midi popped out of the woodwork to let me know the fruits of the research that she, and a very helpful Devon Online Parish Clerk (OPC), had put together in the search for her 3*great grandmother, one Thomasin aka Tammay aka Thomazin aka Tamson etc etc etc YEOMAN.
During that research she happened upon the 1861 census entry showing one of Tammay's married daughters, Jane WALTERS, in the family of Nathaniel DAWE and wife Tammay, in Plymouth, showing as a daughter of Nathaniel's.
Not that I'd searched particularly concertedly, but on the information shown I'd never managed to find Jane DAW(E)'s marriage to WALTERS, nor her birth, nor the marriage for Nathaniel and Tammay.
Knowing what I now know, out they popped:

• "daughter" Jane's 1848 marriage as Jane COTTON to William WALTERS (at least the husband had been correct all along thankfully)
• Jane's 1817 baptism in Plymouth Charles, father Sampson COTTON a miller at Lipson Mill

both images now being available on FindMyPast. 

Midi supplied both of Thomasin's marriages (which images I've not yet managed to find on FindMyPast):

• firstly to Sampson COTTON in May 1816 at Charles the Martyr, Plymouth
• secondly to Nathaniel DAWE in May 1824, Stoke Damerel.

Adding that Sampson had died in 1822 and was buried at/from the Ebeneezer Methodist Chapel in Plymouth, aged 34. And that son Samuel COTTON was a witness to the marriage of Nathaniel DAWE junior's marriage in 1855.
In my defence, I did have a note that possibly the marriage to Nathaniel might be around 1825 rather than 1816 given that's when the next children arrived, but I'd obviously not searched hard enough back when I had access to the Plymouth/Stoke Damerel parish records.

Jane WALTER's family will continue to be included in my WorldConnect database LornaHenderson, so that the research that has been shared  by/with me over the years down that line still shows, but they are now COTTON, not DAWE, descendents.
In the process a few other COTTONs in the database have had their dates checked and approximations now match reality, the family of James COTTON (b. Sth Africa) and Hannah Emma Jones BROOKING. Also added three more children into the family from the 1911 census, which included a 1 month old mite Emmie Violet, crossed out, who turned out to have been born and died the year before.

The database has been reloaded to reflect all of the above, along with the recent activity on the family of Alexander HENDERSON of the P.O. Buildings, Biggar - although several of the newly identified twigs are amongst the living and thus not shown in this extracted database. Would love to hear from the children of Alexander's son Alexander in California.
