I happened to run across the name of Michelle Brand (also wife and colorist Michelle Wrightson, who I mentioned earlier in the topic) and was surprised to see she died also, in 2015.

In the link, she is shown with her first husband Roger Brand, and like herself was also an underground artist.

She divorced Roger Brand in ("circa") 1974. And married Berni Wrightson sometime later in 1976, and they too later divorced at some undisclosed date.
