Hello Gillian.I live in the West Midlands and I have info on this line of Exalls.
One of Henry Joseph Hollands sons was my G.G.Grandfather and lived in Maesteg in Glamorgan.His name was Henry also and he had a son William who is my G.Grandfather. William was a steward of a social club and was tragically burnt to death in a fire at 13 Commercial St, Maesteg. Williams' son, Albert was my late grandfather.Please e mail me if I can be of any further assistance.I'd love to know a little more about H.J.H EXALL if you can help.Thanks.
