How I Found Out I was a Lackey

My name is Dennis Gillaspie. I began my journey into family history about 30 years ago, and in that time, I've faced the challenge of uncovering the parentage of my 2nd Great Grandfather. This struggle is not unique to me; many others in the Gillaspie genealogy have encountered the same brick wall. Andrew Gillaspie was born on February 12, 1796, and according to the 1850 Census, his place of birth is listed as Tennessee. Unfortunately, no additional documentation exists regarding his birthplace. He married Minerva Nichols in 1821 in Wayne County, Indiana, and they had nine children, primarily in Fountain County, Indiana. Later, he married Mary Ann McIntire in 1845 in Schuyler County, Missouri, and they had five children, including my Great Grandfather, Alfred Gillaspie, who eventually settled in Monroe County, Iowa, where he passed away on February 19, 1856. Recently, I ordered a 700 marker YDNA test through FamilyTreeDNA, which revealed that around 1650, a gene mutation occurred in the Lackey male line, resulting in a new branch of that family's YDNA (DNA passed from father to son). After this mutation, a male Lackey carrying the gene changed his surname to Gillaspie, marking the origin of my lineage.
