That looks like the sons address to me after taken a closer look. The is in his wifes maiden name, Simonetti and it could be his mother that moved down that way from Hopewell Jct, NY some time ago. Her name now is Jean Marguerite Thew. You didn’t find the telepone because it’s non pub in the wife maiden name. If I call them, they might get mad at us. Hopefully they will answer your letter.
