Thank you for the reply. I am not a direct descendant of the HINTZ or MARACH surnames, and back in 2011 was helping another researcher with ties to someone in my tree.
It appears that there may have been a few "Joseph Hintz" born about 1895-96 living in Chicago.
I see a 1920 census record for Joseph Hintz, b: 1896 living w/ parents:Bernard+Julia Hintz.
In 1910 Census record for Joseph Hintz, b: 1896 living w/ mother Matilda Hintz (Widowed). This is the Joseph that is connected with my tree.
I would be happy to share the information that I have. My E-mail is: family2find (at) hotmail.com
