Elias had arrangements with Bartholomew for the care of Bartholomew's children when Bartholomew died. These arrangements were cancelled or invalidated by court order after Bartholomew's death.
Given the above, it seems highly likely that Charlotte and Elias were
children of Richard's.
About 1820 Eli moved to Fayette Co., IN. This is about the same time that Jesse Osborn(below) moved to Fayette Co., IN. After just a few years Eli returned to KY. From 1824 to 1829, Eli again appears in the Owen Co. tax rolls. In 1830 Eli is enumerated in the Grant Co., KY census. From 1837 Fayette Co., IN land records relating to his father-in-law Joseph Hawkins, it is clear that Eli had moved to Fountain Co., IN by 1837. About 1852 both Doctor Frank and Richardson moved to Fountain Co., IN where Eli lived.
Given that Eli Osborn early lived near Richard and later in Fountain Co.,
IN Doctor Frank and Richardson moved to the vicinity where Eli lived,
it appears highly likely that Eli was also a son of Richard.
