The DAR web site allows research by non-members, and shows the linage for each application made based on that specific individual. For example, here is the page for Andrew Boyd, b 1747, DAR Ancestor #A013001: http://services.dar.org/public/dar_research/search_adb/?action=full&p_id=A01 3001 This page say that his wife was Sarah Ross. It shows two children, Jane married to JOHN C. GILLESPIE, and JAMES / [1] ELIZABETH POLK HENDERSON. You can then check each of the linages submitted to find descendants of each couple. (Unfortunately for me, no one has submitted an application on my specific Boyd line) John
