The 1901 Cenus for Tipton, Staffordshire, England has Richard Humphreys, born c1853 in "Cefn, Wales".
His occupation is "Boatman Canal". This points straight to "Cefn" being "Cefn Mawr, Denbighshire, Wales" which is on the Shropshire Union Canal (although that branch is now known as the Llangollen Canal).
The rest of the family were all born, and baptised, all along the canal system of England (Middlewich, Wednesbury, Stoke, Saltley, Weedon and London). This could mean that Richard had no connections to Wales, he was born in Cefn Mawr simply because the boat he was on happened to be there at the time??
The 1911 Cenus for Birmingham, Warwickshire, England has Richard Humphreys, born c1859 in "Cefn, Wales". He is the Captain of the "Brentford", moored at Bordesley Street Wharf with his new wife Charlotte (born c1850 Brierley Hill). They had been married for 6 years. Registers show they married in Paddington Green, London, England
Unfortunately I can't see the family anywhere before that 1901 census!!! Some of the children do appear on later censuses though.
Several others are researching the family on Ancestry, but making a bit of a dog's dinner of it by choosing the wrong "Cefn"!
