Frances Clara Folson has the distinction of being the only First Lady of the United States to be married in the White House. On 2 June 1886, she wed President Grover Cleveland.  Our MRCA, William Holbrook (1620-1699), my 9th great grandfather is well documented along my lineage.   Cousin Frances’ lineage was presented in a clear manner without those pesky PRIVATE place holders.   Once I have confirm that lineage, I will be able to claim the youngest First Lady of the United States as a cousin.
