Hi Bram
Yes you would be able to obtain a certificate if we could find a Thomas- Catherine marriage, but so far, no luck on that one yet.
They might not have married of course. I understand that they often didn't make it official for second marriages, for one thing on account of the cost.
My imagination has been running away with me on Amos Evers though...here goes, but remember I am being fanciful...
Could the father's name on the cert read Amos Evens/Evans?The handwriting can often confuse and an 'n' can resemble an 'r'?... Just a thought.
Now, if we follow Amos Evans...
There is an Amos bapt 1826 in Berkshire, Thatcham 11 JUN 1826
Father: Amos Evans Family
Mother: Sarah
In the 1841 census in June, he is 15 and at home, but in 1861 he is 34 and visiting Thomas J and Elizabeth Powell in St Julian's in Shrewsbury. He is entered as married, but wife not there with him. He is a Railway Contractor.
RG9/1871/33 p 6
There is a marriage for him in 1860 Marriages Jun 1860 (>99%), but there is a female spouse missing off the page - but I think it should be Harriett SMITH, transcribed as Shrewsbury 6a 255 .
EVANS Amos Shrewsbury 6a 1255
EVANS Edward Shrewsbury 6a 1255
FARR Hannah Shrewsbury 6a 1255
Now, thinking back to the Ann Bailey we found in 1841 living in the same household as an ag lab, Richard Powell aged 15 or 18, if you look at the original.
Now, could there be a link between the Evans and Powells and could Amos be visiting the Powells later that year and being the same age as Richard, meet our Anne?
She is obviously several years older than him of course, which could rule the scenario right out or could explain why it never was regularised? Maybe both parties fibbed about their ages??
Amos also has a younger brother called Alfred.. maybe your Alfred was named after him,maybe?
Not sure how the birth of John/Joseph Bailey fits into all this, but maybe his birth certificate would reveal the father - unless all you get is a ' - ' for father's name. However that could be quite costly ordering from abroad.
But remember, this is just me thinking very much outside the box.
And 73 is not old!
