Barb, Thanks for the information. I know the NY Historical society has 15,000+ items on the Van Ness family (Peter and his children - including Cornelius and John). I was searching their site again for more detail and found this link that lists related families including Philip and Worthington. Eliza is specifically listed and also a John G. Worthington, who was a lawyer in Cincinnati. I am still not sure how my Henry Van Ness got to Cincinnati and this could be that lead.
There is also information on David Burnes and daughter Marcia.
