There are actually two Abraham Luzader monuments at his gravesite in Guernsey County, which is now in Salt Fork State Park. The first marker (which is very legible) was erected in 1938 by the Cambridge DAR chapter; it reads:
ABRAHAM LIEUZADER CLARK'S VA. TROOPS REV. WAR DECEMBER 14, 1826
The second monument, source unknown, has apparently been erected within the last few years; it reads:
ABRAHAM LIEUZADDER ONE OF 176 MEN UNDER GEN. GEORGE ROGERS CLARK DEFEATED THE BRITISH AT KASKASKIA, ILL. NORTHWEST TERRITORY REVOLUTIONARY WAR BORN 1757DIED 1826 MARRIED LEAH HOGUE 1786
The Lieuzadder spelling appears in several Revolutionary War records for Abraham, who was my 4th great-grandfather. My theory is that someone, perhaps an officer of French descent, enrolled him. I'm pretty sure Abraham was illiterate, as his 1826 will notes "his mark" at the end (rather than his signature). The will spells his name LUZADER. His widow's 1846 pension application uses the Lieuzader. She also "marked" the application.
Abraham's children were Martha (Patty)(1791), Elizabeth (Betsy)(1788), Mary (Polly)(1790), Nancy (1794), Rachel (1796), Sarah (Sally) (1798), Isaac (1799), Leah (1802), and John (1808). These dates are from a 1928 DAR application, so may not be accurate; however, all the names appear in the will.
