Lucretia Rudolph Garfield, wife of President James A Garfield, was the First Lady of the United States for a very short time (March 4, 1881 – September 19, 1881) due to the assassination of her husband shortly after he took office.   The pedigree chart for Lucretia (I think the Borgia family forced that name to go out our circulation) is fairly straight forward.  My pedigree to the MRCA, William Ward (1603-1687) requires a great deal more research on my part since I only have evidence to my 3rd great grandmother, Esther Clark.   There are 6 generations to get to the MRCA!  The lineage for Lucretia is fairly simple and clear except for the unclear use of surnames for the females in the line — it appears whatever tree We’re Related used did not adhere to the standard of using the maiden name for females and may have used the married name for a generation or two.   This will also require research as there are other explanations (i.e. lack of marriage).
