Hi Sara,
So interesting to find you. I am searching for information about this family. Walter F. Cullen was my great grandfather (Edward J. Cullen)'s brother.
I know very little about this side of the family--my middle name is Cullen, though, so I have always been interested in learning more about them.
I am also a part of a big effort to complete a tree of the first of this Cullen line to come from Ireland. I'm not sure if you are interested in any of that, but I am happy to share--and there is much to share.
Anyhow, do let me know what you are interested in learning about this family. Your original message was posted in 2007, so thanks for the patience!
It seems that your branch is from your grandfather John. I do not have any information about him or his children, so I am eager to learn more about their stories.
Looking forward to hearing from you soon.
