My 7x great grandfather appears to have been a farmer judging by the will and probate file I found at AmericanAncestors.org. I found information about his family in an article, FRANCIS WEST OF DUXBURY, MASS., AND SOME OF HIS DESCENDANTS. By EDWARD E. CORNWALL, M.D., of Brooklyn, N. Y. from The New England Historical and Genealogical Register on Googlebooks:
