Thinking further, would I be right that your Crowes have some relationship by marriage to the Corletts of Loughan y Yeigh ?

If so, that is quite interesting, as I recall my mother saying that there was a very distant connection, with the Crowes. I gathered that it was along the lines of "A" married "B", whose brother or sister, "C" married "D", whose brother or sister etc etc. I wish I had noted down everything she had said, or better still taped it, but .... !!
