Welcome to Wikitree, Dianne!
If you use the search box at the top of your profile, you can find other members with the same surnames you are interested in. Put a surname in the surname field and leave the other field blank and you will get a page like this. Click on the word genealogists to find other members with that surname.
Better yet, upgrade to family member. Then you can start adding your family and discovering your family story. It is free to upgrade. When you upgrade, add tags to your profile. Tags become clickable links to other members interested in the same topics as you.
Good to have you aboard!
