I am not related to the Frederick Stephens Family,but there more than several families on Ancestry that are. You can access them by doing a general search for Frederick & Hulda on Ancestry. The Goodwin Family seemed to have the most information.A couple of families had Hulda's birthplace as Liberia in 1815,
These families are mainly Canadian and I'm not sure you can access them if your subscription is only for USA. If you don't have access, I could send a message to the owner of the Goodwin Tree, although the owner hasn't signed in for 3 mos.
