Augustin Family Genealogy Forum
I have a little information from an article reprint from "The Long Island Forum", Winter, February 1, 1988 on "The Augustins. A Grand Old Hicksville Family" (note: that's Hicksville, Long Island, NY), written by Helen Hiscock, as told to Val Conover.
Since I'm searching for info on this name too- I would be glad to post more of the article. This article is mainly about early Hicksville, and Frederick Julius Augustin, known as Julius, who was born in Hanover, Germany in 1838 and his older brother William Augustin. William and his brother first had a store in Greenwich Village, NYC. William died in 1867. Julius kept the store and business until 1872. He married Johanna Freytag whose parents lived in Hicksville. When she died following the birth of their daughter, also named Johanna, he moved to Hicksville to be near the Grandparents.
From 1874 to 1890, he ran Augustin's General Store, Broadway and Marie Street, Hicksville, Long Island (Queens County), NY.
