Thank you. Always looking for good sources. Mostly I use Wikipedia Commons. I've collected old portraits of my ancestors, which is quite fun. I prefer finding the women because it's harder.

The Livingston family portraits are a funny story. I found images of these in b/w in an old publication and colorized them. Then I was invited to one of the mansions in the area and brought along my colorized copies to show the owner. She started laughing and took me into the hallway to see the originals.
