I Googled "Mr Mrs and Miss Schoolding" Dublin
Quite a few hits. I tried to get the link for one which is for the
"Biographical Dictionary of Actors Vol 13 ROCHE to SIDDONS" but the link was
about 7 lines long. So if you google that you will be able to read quite a
bit about them.
Mr and Mrs S were in Joseph Ashbury's company at the Smock Alley Theatre
Dublin in 1698-1699.
My friend GOOGLE rarely fails me.
