Re: duckworth family of Maryland

I am searching for information regarding my great-great-grandmother.Her name was Anna Duckworth.She married John Stark.My great grandfather was one of thier sons.He is Orville Stark.I believe they are of the same descendents because all of the above are from Allegany County Maryland and most of my relatives are there and in Garrett County Maryland.I don't have anything else.We are working on our family tree for a school project and we need to go back to where our descendents immigrated from if possible.If you have any information on Anna Duckworth Stark, please post it.Thanks.
