My wife and I both have separate FamilySearch accounts.
Am I able to share a living person I've added, so my wife can see this same living person using her account?
Or does my wife need to recreate another living person with the same details?
You cannot share living. Anyone living is in your private space so you wife will need to create that person if you choose. But remember you are just making a copy that someday will need to be merged. Also recently at Rootstech they announced that shared living space is being worked on and maybe available in the future if you want to wait and watch for that.
Thank you Cindy,
I'll wait then... Hopefully, it's in the near future.
@Wayne M Norton There's a mention in this blog post of the feature Cindy referenced:
It looks you can do it now over at Ancestry.
