Yes I do mean genealogy, sorry I think that must have auto corrected!
Hi B & welcome to RC 
Can you please give us the names of your grandparents & all the details you can from the marriage cert. please (assuming they were married in Scotland)?
Where were they married would be the 1st thing to look at & what were the addresses of each on the marriage cert?
What were the names of their parents given on the marriage cert. as this will help locate them in census records?
Depending on his father's occupation he may have moved around?
Did any of the children have any unusual or less common names which would be easier to look for?
Do you know any of their yrs of birth or guesstimates & names in order of eldest to youngest which can be compared with RD of births?
Please do not post the names of any possible living people though, only people you know to be deceased.

My Grandparents names were John Cameron born 14 October 1934, and Patricia Mary Cameron (nee Folan) born 30 March 1936 in Old or West Kilpatrick in Scotland. I don't have the marriage certificate, however from my Father's birth certificate it says they were married on 10 April 1955 in Renfrew, Scotland.
My grandfather's occupation on my Father's birth certificate is listed as a ship steward. I also know that his father was also called John Cameron, and his mother's name was Mary (although I do not know her maiden name - it may have been some variation of Morris).
I know the children's names, however they are all still living, and as such I won't post their information. However, it may be of note that both my father and I have the middle name Saith. Although I can't find any John Cameron's with the middle name Saith, so it may not be much help.
Hi BCameron,
are you in the USA?

No, I am based in Australia, my father's family immigrated here in the 1960s. My grandfather died here, however the laws here are very different to the UK and they will only release copies of death certificates to the next of kin.
Is Um a word?
Maggsie
It's an interjection.
BCameron,
Does the form specifically ask for town of birth? A birth would have been registered in a district. Do the forms ask you to supply your grandparent's birth certificates?
The form's do specifically ask for town. From my understanding, a district in Scotland is essentially a town? My Father's birth certificate says 'the district of Paisley' however Paisley is a town/city. I don't need to their birth certificates, just their place and date of birth.
It seems ridiculous that I have so much information on them, and still can't figure our where my Grandfather was born or what 'John Cameron' he is on the list of Scotland's People!
