Marvel Chronology Project

I'm currently reading Marvel Masterworks The Incredible Hulk vol. 5. At the beginning of issue #115, General Ross contacts Avengers Mansion with a question for Rick Jones about the Hulk. He reaches an unnamed "cleaning woman" who refers to the apparent death of Captain America in contemporaneous issues when Rick was the new Bucky. Someone on Pinterest identified this character as Frances MacDonald. There is no entry for this character in the MCP. Does anyone know the source of this who can put together a chronology for the character?

The wiki lists her but doesn't give the origin for her identity. Maybe an index?

The character name was added to the Hulk #115 wikia page in August, 2014, by HamsterMan.

Searching Google for "mary frances macdonald" "marvel" yields only the pinterest page and the wikia page. The pinterest page is a direct swipe of the wikia page.

I'm guessing that HamsterMan just made something up.
