Andrew Dunn:
Sam Williamson was a foreman riveter who had his own squad. They worked mainly in the Govan yards, but Sam went to work in Peru for a short time. While there he became ill. Local masons paid for his treatment and helped pay for his return to Glasgow.

Louis Dunn:
I remember in the house, when Anna was with us, that there were some Masonic jewels and Lodge certificates from Valparaiso and maybe Montvideo.
