Photograph of John Leander Porter/Pothier

Question

I am looking for a photograph of a John Leander Pothier It appears the only surviving family would be that of his sister Irene M Pothier who married a George D LeBlanc. They lived in Lynn, Mass many years until their deaths in the 1980's. I am wondering if they had any children who may have a picture of John. Some in the family anglicized the surname to Porter.
