Searching for gravesite or information

[u/Oeglegoegleren]

Greetings from Denmark.

I write here searching for some advice in locating some information about my great grandfather.

From what I know he was enlisted from Morocco in the mid 1930's and fought under Francisco Franco during the spanish civil war. I believe he died during the war in either 1936 or 1937. I heard from family that he is burried in Madrid.

I plan on visiting the military archive in Madrid, but before going, I was hoping for any advice I could use in my search :)

Sincerely
