California Death Index: Henry Franklin Suydamb. 11 May 1862 Illinois d. 25 November 1942 Mendocino County, California no parent's names given
I did find Henry's parents, Henry R. Suydam and Sarah E. Rodenbaugh, who were married 1 Feb 1860 in Fulton County, Illinois. And, Henry's information regarding his service in CO D 103rd Illinois Infantry and subsequent deathon 31 December 1863 in St. Louis, MO. After hunting around and finding the families of both parents, and Sarah's remarriage to Nathan Messler on 13 May 1866 in Fulton County, IL, I discovered that you already had all of this information posted on Ancestry.com.
