When looking on Scotlandspeople, use a wildcard for the surname as there are several variations of the name Bryden (depending how it was transcribed). A RootsChatter kindly looked up a birth for me and eventually found it with the spelling of Brydane, the way it was pronounced. Unfortunately us Brydens seem to be an elusive lot.
Best of luck
