Hi
Can now confirm picture is not of Cae Goronwy or Llys Twrog. Have not heard from my friend, but now realise that he would have been busy last few days. Have also checked out Meillionydd which you mention in another posting. There have been so many alterations/additions to this property it's difficult to work out what it originally looked like, but am pretty certain it's not the property in the picture.
On the positive side I've found an article in the On-line edition of the Dictionary of Welsh Biography, about the brother of Rev Stanley Haydn Williams, William Ewart Williams. I've had a problem creating a link to the website, but if you put "william ewart Williams" into a search engine, you'll find the website, National Library of Wales :: Dictionary of Welsh Biography. Click on 'W', then scroll down to 'Williams, William Ewart', you'll find that he was a distinguished scientist involved in the American missile program. It mentions his brother Rev Stanley, and another brother Robert Arthur Williams of Sydney, Australia. There is also information on the parents and of the family grave.
According to the article, the family home was Bodgarad, Rhostryfan. As I was going thro' Rhostryfan today (Sunday), I decided to have a look at the property. The last few hundred yards is along a rough farm track and I decided not to take my car along it. As it was raining quite heavily I decide to leave visiting it until I get a dry day. Forecast for this area is reasonable for tomorrow afternoon. I have walked past the property a couple of years ago, but don't remember what the property looks like. I'll also have a look at the family grave at Carmel sometime during the week. I only came across the article today; I was jogging/walking within about 100 yards of the cemetry yesterday.
According to the article, Llys Twrog is the Rev Stanley's mother's home.
