I do like your suggestion and will soon begin to contact my former clients.
On my website, I have asked my clients what they would like me to name their painting.
I ALWAYS suggest that the first and last name of a child not be published

. Long ago, my 6-year-old son got his picture and name in the newspaper and the result was that he was stalked by a pedophile. I was scared to death....and it went on for a couple of years.
I often letter names into my portraits, but it is (intentionally) nearly impossible to read them online.
