Hi - I'm also a descendant of Edward and Mary Ann Turley their 6th child John was my Gt gt grandfather. I also believe that Frank was Margaret's son. I have done research on the Turleys and hopefully have matched up the families as best I can. There was a period when there was an explosion of Turleys on Viney Hill - it felt like nearly every other entry in the parish records was a Turley and then complicated by repeated first names. I can let you know the names of the spouses of Johns siblings.
Hope this helps.
Regards
Paula
