I am looking for information about Nickolaus (Nicholas) and Katharina GUCKERT. They were born in Bavaria, presumably in the region that became Rheinpfalz. Nickolaus GUCKERT was born September 8, 1808. I do not know the names of his parents. He immigrated to the United States along with his brother, Valentine GUCKERT in 1838. They settled in the City of Allegheny, Pennsylvania. Katharina GUCKERT was born on April 5, 1812 and died in the United States on January 19, 1886. I do not know her maiden name. I am looking for marriage information about Nickolaus and Katharina as well as the identity of their respective parents. Thank you.
