a font question

[ratcreature]

I created an artwork last November, which is one in a series. It used a particular font, but I can't remember what that font was. Unfortunately that was created on my now dead, previous laptop. I now want to make a new artwork in the series and need to use the same font, but it apparently wasn't one of the standard fonts (though I'm sure it was a free font), because when I open the old XCF file, Gimp does not display the name of the font, but it is blank. Is there a way to get the name of the font I'm now missing from that old file so that I can download the font again?
