Thank you for posting that.
The hard thing is finding Anthony Hickman as a child, his father is supposedly William and I can't find Anthony's death date in Rhode Island. There is also a Stephen Hickman who was in Rhode Island as early as 1870 on the US Census in Providence, RI. What happened to Stephen, as he was 60 in 1870.
The family is very interesting in that this branch of Hickman's appear to be free people of color as early as 1840.
