Should be my 4th Great Grandmother but shows "Christina Jacobsdotter Ekström is your uncle's partner's husband's sister's husband's third cousin twice removed's wife's great aunt." ??

I was going to refresh the path, but it looks like this is cleared up as it's showing me the correct relationship to you.
That was interesting. I had looked at the path from him to you and it showed you has his 4th great grandson. But I looked at it now from you to him and it showed as you stated, which is odd. I refreshed the path and now it shows correctly to me.
