Wow, Lisa! It's amazing to have a descendant of a Titanic survivor on board. Welcome to Encyclopedia Titanica!
I, too, have been searching for a photo of Julia Smyth, because I am very interested in the child and teen survivors of the wreck (she was 17.) I recently found out that a photo of Julia can be found in the book The Irish Aboard Titanic by Senan Molony. I do not know how old she is in the photograph because I do not have the book yet.
Yours in obsession with the Titanic,
