This font is made more difficult to identify by the fact that the original font used—and the second date added to Margene’s side at a later date—are actually two different versions of Baskerville. This can be seen by looking at the two different ‘4’s used in Margene’s years of birth and death.
The original version is Baskerville ACCT AK Rev B in Gerber. I am unaware of any other version of this font outside of Gerber.
The March date added later appears to be Libre Baskerville.
This job will need to have a mixture of the two fonts in order to not be noticeably different.
