I think I have the dates right. He married a Fanny Threadgold in 1923. There is a poem in the first volume of Threshed Wheat by a W.Threadgold .. which I assume is her father Walter. Appears he was the UK distributor for Light and Liberty. Anyone know more about him?

Would be good to get a scan of the the book you mention if you get time.
