Argument for "Leaner":
'Leaner' is used twice in the notes regarding a property dispute where Lerner and Sampson Stevens "who are complainants against the other heirs of Abraham Adams and involve sale of land and slaves owned":
"Leaner Stephens the wife of Sampson Stevens"
and
"Leaner married Sampson Stephens"
