Hey Janet
From "Pennsylvania German Pioneers" compiled by Ralph Beaver Strassburger and William Hinke, the name Christian Gutknecht appears on list 130c, ship Christian, which arrived in Philadelphia on September 13, 1749. Christian made his mark by his name. The "Pennsylvania German Pioneers" is a three volume set which includes names of ships, passengers, their oath to the English Crown, the name of the ships captain. Unfortnately, in most cases, only the head of household is named in the lists. Try this URL
