I wasn't sure if a connection to Abraham Lincoln had already been found, but I found one, so thought I'd post it:
Abraham Lincoln -> his father, Thomas Lincoln -> his father, Abraham Lincoln -> his father, John Lincoln -> his father, Mordecai Lincoln -> his father, Mordecai Lincoln -> his father, Samuel Lincoln -> his mother, Bridget Gilman -> her father, Edward Gilman -> his brother, Robert Gilman -> his daughter, Mary Gilman -> her daughter, Hannah Jacob -> her daughter, Deborah Loring -> her son, Elijah Cushing -> his wife, Elizabeth Barstow -> her father, Joseph Barstow -> his father, Joseph Barstow -> his sister, Sarah Barstow -> her husband, Nathaniel Church -> his brother, Benjamin Church -> his daughter, Elizabeth Church -> her daughter, Hannah Rosbotham -> her son, Nathan Munro -> his daughter, Lydia Munro -> her son, Squire Humphrey -> his daughter, Sarah Humphrey -> her son, William Crowley -> his daughter, Nellie Crowley -> her husband, Edward Kuntz -> his sister, Emma Kuntz -> her daughter, Georgia Ferrell -> her husband, Irwin Hirsch -> his mother, Harriet Friedenheit -> her sister, Sophie Friedenheit -> her daughter, Gertrude Kingsbacher (A.J.'s great grandmother).
So by this line, Abraham Lincoln is 37 steps away from A.J.!
