lol Idont have any either Bleckie!
I have tried the same methods as you have used and still getting no results. I find it really odd that their childrens birth certs have got their parents marriage dates on them. I found this out by visiting edinburgh register house and looking at a ll the births. You have to order them on SP but you can look at them online in the actual building.
The problem Im having at the moment is discovering if I have the right family to continue researching this line.

I wish to find info on William Campbell born 1905/06 in Glasgow. He had a sister called Maud and I was able to look at 1911 census for this brother and sister. One family have William and Maud with parents James Campbell & Matilda Jane Mckeon ; William J being born 27 MARCH 1905, and the other family is William James Campbell & Mary Stuart. Im sure I have picked the correct family of being James & Matilda, so this is why I am trying to find the marriage of William Campbell & Elizabeth Gibb (1908-2001) to get the correct parents or even getting hold of his death cert.
Many thanks for looking anyway, sometimes it helps having a new pair of eyes searching
