Changing her name can be bad luck if you don't do it right. Look up the name changing ceremony by John Vigor and follow it exactly.........especially the part where large amounts of alcohol are consumed.
You need to ensure that all of the old gods are happy about it.
If you need help with that part (consuming the alcohol) I am sure there are members here who would love to help.
Anyway, sorry I have no experience with a project like you are describing. Good luck with it, and keep us posted if you have the time.
