I just saw a blurb on facebook from findmypast stating that they have photographs online and they can be found in hospital and prison records; passport applications; business directories; military records and off course newspapers. So I select the first one - hospital and prison records and did a search for Palin.
One of the first named results was an Alfred Palin. I immediately thought of the Alfred Palin that was a bigamist that I blogged about Dec 8 2016. Perhaps that is why he seemed to disappear from official records. What I found was amazing - not only is there a picture of him but also his whole penal record - even showing years of incarceration.
