Do you know for sure that he was born into a Rylett family? and then adopted by Ryletts? I know that James Rylett(brother to Thomas and Charles)and his wife Florence both died within months of each other in 1920. Is it possible that they had a son and he was then taken in by Thomas and Hannah? The timeline for Charles and May Rylett doesn't fit as Charles was in Manitoba on the 1911 census and as far as I know was there for a few years. Hope this helps.
