what gertrude and jacob? they were brother and sister. you have that. children of johannes pulver b 1679 and anna catherine busch were michael m anna catherine mohr, peter m sussannah drumm, jacob m maria christina bernhardt, conrad m magdelena schafer(shaver), gertrude m jurey (georg) jager and anna margarteta who did not marry.
