Hey Pamela, your husband and I are cousins!
We find that a lot of the information in other people's trees (on Ancestry and other sites) is not reliable. The technology makes it very easy to copy mistakes and share them over and over, without realizing that they are mistakes. Dorcas Getchell is one of those. The Getchell and Wooden families have been studied pretty thoroughly by experienced researchers (which is amazing!) - if there was any evidence for Dorcas being the daughter of John Wooden, they would be the ones to find it, but they didn't - in fact they found evidence that she can't possibly be.
So, calling her "Dorcas Wooden" is a mistake which people have innocently shared. If you look at what Jillaine wrote above, you can even see how it might have happened - John Wooden #2 had a daughter named Dorcas - even though she is the wrong age by about 50 years and married someone else! Someone made a guess and it was wrong. It happens.
This means we simply don't know (yet!) who Dorcas Getchell was before her marriage. But there's a lot to learn about Samuel's family if you are interested! :)
