Seeking more information on Lorenzo P. Alexander, born 1821 in New York and his wife Rachel Cooper, born 1822 in New York, possibly Allegany County. They were married 13 January 1842 in Berrien County, Michigan and appear there on the 1850 Census with the following children: Theodore, born 1842 in Michigan and Emily C., born 1850 in Michigan. Rachel's possible sisters resided with them, Emily J.(Jane) Cooper, born 1830 in New York and Catherine D. Cooper, born 1832 in New York. Emily married Perry Fox in 1850 in Berrien County, MI and Catherine married Alfred E. Egbert in 1853 in Berrien County, MI. I speculate Rachel's parents to be Price Cooper, born 1789 in New York and Lydia Chapman, no vitals known. This Price Cooper lived two doors down from Lorenzo and Rachel (Cooper) Alexander in the 1850 Berrien County, MI Census. Any clues appreciated.
