I have some magnificent botanical artwork that is signed and dated. The name is unique enough that I believe I have found the artist - an "everyday person" from 100 years ago in a rural area. More looking turned up some ancestors and descendants - now I have 5 generations of this family. I'd like to start a tree for this family and see how far it goes - perhaps as far as a living descendant that would like to know of the artist in their past.
My question is: How do I start a new tree that is unconnected to my family? I don't want to affect all the work I've put into my family research.
