Diana, go to your profile page

https://www.wikitree.com/index.php?title=Special:MyConnections&w=Holland-6073
That page has the names and WikiTree ID's for 607 people that are already entered on WikiTree and are connected to you either directly, they could be several generations of grandparents, aunts, uncles, and cousins or they could be in laws of many sorts, they are connected to you by marriage, such as spouses of various generations of aunts and uncles, cousins.
It probably isn't a complete list, on your own profile you can click on ancestors and will see several generations of direct ancestors that already have profiles. after you upgrade to Wiki Genealogist by signing the Honor Code you will be able to edit any open profiles, you can add photographs and information to those profiles
You will be able to contact the people who created those profiles and find out how you are connected to them either directly or by marriage.
It is one of the best parts of WT, finding other people who share ancestors with you.
We do not create duplicate profiles on WT.
If you need more information, please ask
