I didn't come across the name in the birth, marriage & death announcements in the Glasgow Herald 1904 to 1906. I had already done 1907 to 1914 before I saw your post. I was searching for the Gilmour name, so it didn't put me out at all looking for the Gildea name.
If, like me you are desperate to find someone, the Glasgow Herald archive can be found here
https://news.google.com/newspapers?nid=GGgVawPscysCIt's on line until 1900 with the British Newspaper Archive & FindMyPast.
The Google archive is incomplete, issues missing or so badly scanned they are illegible, but it is free and their archive goes up to 1990.
I believe there are new parish records going on line at Scotlandspeople in a few weeks time. You might have some luck with this new archive.
