I did a Goggle Search "Charles M. C. Doran", 1876-1935, coming up with the following hits. He would have been the appropriate age to have served in the Spanish American War. And, he could very well have served in WWI.

Charles M. C. Doran passed the examination for admission to the bar of the Supreme Court of the District of Columbia [The Albany Law Journal ca 1899, page 207] See:
