Dean's middle name and John and Mary's wedding date

[eloise_bright]

First post here - I discovered this comm a few days ago, through the Supercanon wiki page, and it's a mine of information.

I'm looking for a couple of bits of info. Firstly, I was wondering if there's a copy of Dean's birth certificate online somewhere. I've hunted at the offical site, and checked Supercanon, but I can't find anything. I'd like to know if Dean has a middle name - the nitpicker in me wants it to be canon.

The other thing is the date of John and Mary's marriage. Or info on how many years they were married before they had Dean.

Thanks in advance!
