After going over my notes regarding George Etherington he was born about 1877 and according to his marriage cert. his father was called William (deceased). His birth year appeared to match that of being the son of William Etherington and Catherine Ramshaw. Although it would be nice to confirm that information.
Regarding John Etherington, I had wondered whether the couple were close friends of my Nicholsons or whether it was just the short time they lived in Shotton.The mining community was very transient at times.
