If you live in Glamorgan, why marry in Reading, Berkshire?

[Braban]

After 14 years of searching I finally found the marriage certificate of my Gt Gt Grandparents.

John Morgan b.1834 St Brides Major. Later moved to Coity, Bridgend on the death of his father. Son of John Morgan (carpenter)
Elizabeth Thomas b.1834 Ewenny. Daughter of Thomas Thomas (farmer).

They married in 1866 in Reading, Berkshire at the Parish Church St Mary.

John’s address is given as Coity. Elizabeth’s address is given as Castle Street, which coincidentally is the street where St Mary’s is.

Witnesses to the marriage are: Joseph William Crapp (has the word Clerk written beside his name in different handwriting)
And Friend Clements (Church Sexton)

They are married by licence

After the marriage they move back to Coity.

So my questions are:
1. Why marry in Reading?
2. Elizabeth has no rank or profession and is a spinster at the time of the marriage so what is she doing living on Castle Street, Reading?Her father had died two years earlier but according to the 1871 census her mum Harriet is farming the land in Ewenny with her sons.

3. Could Friend Clements be a Quaker?

4. Is Joseph William Crapp a church clerk?

5. Did wonder if it was a marriage of necessity, but first child isn’t born till September of the following year.

6. Witnesses appear to be neither family or friends.

Any words of wisdom greatly appreciated.

Perhaps there was an earlier child, stillborn and not registered?

According to the 1851/1861/1871 census Friend Clements was a sexton b Sussex.  Living in Berkshire in 1851/1861/1871

Marriage by licence (instead of by banns) means you can marry quickly and with less publicity, which you might want to do if there's a baby on the way.

But just because the bride isn't given an occupation, doesn't mean she didn't have one.  I have lots of relatives recorded on censuses as domestic servants who appear as spinsters on their marriage certs.

Spinster is not an occupation

I think the clue might be that the bride was from a farming family.   Glamorganishire bred sheep and cattle and there was a market at Reading. Reading was a bustling busy place with road, rail and water outlets.  For all we know the husband or the bride might have been taking annual trips to the market at Reading to sell cheese, animals, or even to buy more animals.

There's some literature giving information about Welsh Drovers in the 19th century seen on this url, which might be available to read online:
