To merge your own profiles, you may simply login to one of those accounts and add the email address for the other account.
To do so first log into one of your Geni accounts and go to your Account Settings. Find the Email and Password link and click on it. To add the email address associated with the other account, click, 'Add email' and enter it in. Once you have saved this, you will receive a message asking if you would like to merge your Profiles. All that is required is for you to enter in the password for the other account. Otherwise, you may send yourself a verification email.
