Can Kitabatake Keep Being Called Kitabatake?

I have read the novel "Hagun no Hoshi" written by Kitakata Kenzo, whose main character is Kitabatake Akiie (1318-1338). In the story, Akiie dies at Ishizu in today's Sakai City, not at Kitabatake in today's Osaka City. I wonder how many believe Kitabatake died at Kitabatake.
