BushInn1746 where did you find the marriage licence information I looked on Find My Past with no luck.
Because you seemed confident you had his name correct "Jonas White"
I don't use my f m p app.
Just checked I can still get image again & noted stages.
But on awkward ones that won't return (that I think should), I start fresh from Google
1. search engine "Find My Past" (but do not click the sponsored one).
2. if signed in. On Find My Past click Menu lines (top right)
3. click Search
4. click Records by Category
5. click B M D & Parish
Here you should get the page where you enter search details
6. make sure Britain is selected
7. make sure the one beneath is on B M D & Parish
8. remove All subcategories by selecting 'Parish Marriages'
9. Enter his forname Jonas, but UNTICK because you have exact spelling of Jonas
(That is assuming the site has spelt it correct, but as you know they don't always)
10. enter White in surname (leave on exact)
11. enter year 1836 and
12. make year EXACT (remove -/+ 2 years)
13. click search
Three results.
One of the 3 results should be the Licence image. I have World / Full Membership (whatever they call it)
We have to click the image in England since it was changed
I find with the internet, I can find a document one day, then another day I can't find it ( I wonder if the last search has cleared).
