Ernest and Hedwig Bareiss are living next door to Herman and Mary Maier in Pittsburg, PA. in the 1930 Federal Census. That might be the Maier connection. I beleive I may have found their family register information in Lorch. There is no information indicating that they came to America, however the names match up with the family and dates are correct. Ernest was born in Lorch on June 22, 1902, Anna was born in Lorch on November 05, 1899, and Johannes (Hans) was born in Lorch on May 03, 1898. They had 3 other siblings, two of them passing in infancy. The other was Luisa Karolina born in Lorch on April 28, 1904, she married in 1933 to a Maier.
Their parents were Johannes Bareiss and Karolina Schmid. Johannes born October 14, 1872 and his wife November 18, 1874. Johannes died in Lorch on February 28, 1951 and Karolina died in Lorch on February 5, 1950
