Millard F. Lyst (1856-1886) was the son of John Lyst and Sarah Wilson Lambertson. I found the record of his marriage to Hettie Oliver on December 24, 1878 in Randolph County, Indiana. Prior to searching this database, I didn't have the exact date of the marriage nor Hettie's maiden name. They later had a son named Oliver.
