This is Frank Mattes a photographer in Philadelphia, PA. He was born 14 Jul 1881 in Vesprod, Bacs-Bodrog, Hungary, he came to the US in 1906 and was naturalized in 1914. He married Magdalena "Lena" Teufel and they had a son names Frank Jr who was born in 1912 but died in 1915, and a daughter Anna Helen Mattes, born in 24 Jan 1917 who was still single and living at home in 1940. The last record I have found on Frank is his 1942 WWII draft card and he is still living in Philadelphia.
What I don't know, is how he is connected to my family.
