I saw your post about Share and looked into it yesterday. Right now the Ancestry.com Share-to-Facebook option is only available on the record page (the page with only the index information).
It's currently not available from the image page (where you can view the image and the index). I followed the link in your post, and it seemed that perhaps you may have been trying to share the record from the image page. You should be able to share that census from the record page.
Thank-you very much for your prompt reply. I tried the "SHARE" option as you suggested, and find it works just fine. I wonder how I managed to stumble on the correct option initially?
Perhaps "SHARE" should work the same on both the index detail and the image page, so as to not confuse poor old white-haired genealogists like Ol' Myrt here?
Happy family tree climbing!
