You must build your tree from you upwards toward Euriah. It is unclear if you are a member here as you are not logged in. If you are not a member you will need to join first. You may begin the process from the main WikiTree page, here.
Once you have completed all the steps to become a member and have been confirmed, you can begin adding profiles and eventually be able to connect to your ancestor.
If you are already a member, log in and then add ancestors until you reach Euriah. You can read about adding family and connecting to existing profiles here.
