Kit, I'm glad you have managed to find a solution of sorts.
If Ancestry don't allow more than one one per email address that is something they should probably look at changing. Ancestry should be aware that there is often only one family member who takes care of these things and who has other relatives tested in order to compare results, and if they put hurdles in people's way they will test with another company.
And, as already mentioned, not everyone has an email address.
Ruskie, They have no intention, as far as I can see, of changing it back. There was uproar when the change came in, apparently, but people quickly got round it, by creating new email addresses for themselves. I did it using one I already had.
Here is what DNAGeek said at the time it was introduced, full instructions to manage someone elses account.
http://thednageek.com/upcoming-changes-to-kit-registration-at-ancestrydna-keep-calm-and-carry-on/Here is what Ancestry says -
"Each adult who takes the test must activate it on their own Ancestry account. With the exception of tests for minor children, only one DNA test may be activated on one account. To invite another adult to activate their test, see our article about helping another adult activate a test.
To create an Ancestry account, you'll need an email address. If you don’t have an email address, or if your email address is already associated with an Ancestry account, you’ll need to create a new email address"
So my husband has his own account and email address, I invite him to view my tree. 'He' gives me full access to his DNA results, and nominates me as manager.
It works exactly as if I were managing it from my own account, but he has to have a separate account as well, presumably in case at some stage he wants control of it, which he would otherwise not be able to have.
