Can anyone identify the subject of a bronze bust?

Can anyone identify the subject of the bronze bust on the right, the woman with the initials GRC?

It is a small bronze portrait bust by sculpture artist Catherine Wentworth. Wentworth lived from 1865-1948.

Thanks in advance

The dude on the left looks like a bit like an idealized neoclassical Napoleon Bonaparte. Not sure about GRC, and Google has failed me.

Impressionist, and her portraits seem to show the same lady… so consider it a selfie, an impressionist selfie (can’t be distinguished from also including her family members as the subject, even if its a sister in law or step mother…she might squash non-family into the one model she uses.

There is a photo of her in her studio https://www.loc.gov/resource/ggbain.19089/
short or tied up curled hair. High eyebrows, similar nose, similar chin with the similar smile lines/jowl lines … like in various moods or ages of life … changes the look to be of a thin or wellfed lady, but seemingly theres the same lady in behind the impressionist effects.

random portrait she did. https://www.invaluable.com/auction-lot/painting-catherine-denkman-wentworth-521-c-e4a7caf810 … see the similarity ?

There is a record for the Gorham bronze division …it might provide more clue as to what GRC could be.
