Martin Anderson Lier Valley area to Leer Michigan

Looking for information about a Martin Anderson born approximately 1855, who is thought to have immigrated from Lier Valley Area. Information I have says he may have a half brother Christopher. My gg grandfather Jakob Anderson, maybe his half brother as well. Jakob's parents were Anders Johannessen and Mari Johnsdatter and he was listed as illegitimate. Jakob immigrated to America in 1872. Martin Anderson boarded with my gg grandparents Jakob and Mathea when he arrived to America. Martin then married Rondine Barsen in 1912 in Leer Michigan.
