My husband's family has Disharoons from Missouri.Here is the info we have.
Thomas Disharoonb. MD married 9-2-1840 at St. Louis, MO to Lucy Francis Ferguson
They had Fergus Ferguson Disharoon b. 12-7-1848 St. Louis, MO d. 10-9-1936 Gray Summit, MO married Ella Francis Nunn b. 7-29-1850 Gray Summit, MO d. 4-5-1914 Gray Summit, MO
David Lewis Smith b. 10-22-1869 d. 1947 married Martha Francis Disharoon b. 2-16-1872d. 1938 (I believe they both were from Gray Summit-Villa Ridge, MO)
The above are my husband's great-great grandparents.I may be able to find out more information from my husband's grandmother.I believe there may also be some Disharoons in Arkansas.
Should I assume that the above Thomas is a direct descendent of your Michael Disharoon?If so, could you send me information on the intervening generations?Our email address is firstname.lastname@example.org.
