Hello Steve, Welcome to WikiTree!
Glad you join our community, and to fill in more of your branches. It looks like you have a great deal of work into your history already. Don't worry about learning all the processes and procedures before growing your Tree. Experience is a great teacher. Errors can always be corrected
Questions or concerns can be addressed in 'Intro to WikiTree' found in the 'Help' menu, by asking questions in G2G or asking your Greeter. There are also many videos as well.
Thank You for your kindness Susan
