Hi Jayne,
I emailed a cousin who lives in Chirk and whose father is 91 and asked him to ask his dad for any info about the Holloways. I don't know if he asked his father but he emailed me to tell me that he remembers Ned Holloway well, and that his two sons were called Gilbert and Gerald, and the Glyn whom you thought was a son is actually married to Ann, Ned's daughter. And the amazing part - wait for it - Ann and Glyn live opposite my cousin and he knows them very well and also her two brothers, now sadly passed away. If you want to contact Ann Holloway I can ask my cousin for contact details which I can post to you privately. Small world isn't it.
Janet.
