Elizabeth Foster

I am still searching for the identity of Elizabeth Foster for whom this plant is named. My first thought was that she might be related to H. Lincoln Foster of rock gardening fame.  It is known that he and his wife Laura Louise designed a garden for the Root Glen. But I did not find a connection.
