Hi there - I think my mom may have already contacted you but wanted to let you know that I have the "Whitehouse" family bible that has lineage back to early 1800s but not too much related to Ijams before Plummer Austin.
Let me know if there is anything I can help you with. My dad (Ned Johnson) resides in So. Maryland and Gene is in Virginia...all are happy and healthy.
Good to see interest in the family history! Good luck, Kristen (Ned's oldest daughter)
