Hi Pat and welcome to the forum.
Just to check if you've seen the various Morgan photos, including ferryman Alexander, that Gillian has kindly posted on this site's Gallery ?
See http://www.forest-of-dean.net/gallery/lydbrook_2/index3.html

To help us best help you, and to avoid possibly revisiting what you already know, may I ask if you can please clarify any specific questions you have about your ancestors ?.

Thanks.
