My grandfather, David John Ashton from Wales sang in this group. He was also a coal miner and a Methodist/Episcopal preacher. He married my grandmother, Louenna Hendershott. They were both from Plymouth, Luzerne Cty at well. I can 't find anything on either of them. Do you know any site that may help me at least with the Shawnee Warblers? Thanks so much, Lenore Bradford
