The "hints" in your tree at Ancestry.com can be helpful. The screen shot to the right shows the three hints that appeared for my grandpa Neill's brother, Ralph, born in 1905. The SSDI reference was dead on and the 1910 census record was the right one too, even though it is indexed as "Mill" instead of "Neill"
Bear in mind when attaching these to your tree make certain you choose "alternate" fact where appropriate and always view the advanced options as mentioned in our preceding post
I normally don't attach from the trees, but that is just my personal preference.
