Please consider a visit to Ron Hamrick's excellent site: http://ron.hamrick.net "Hamrick Generations" was republished in 1983 by Virginia Greene DePriest, and contains the following preface: "Mr. Jones believed Hans Yerke Hamerick, who arrived in Philadelphia on the Louther in 1731, to be the common ancestor of all the local Hamricks. He had access to two books, one published in 1852 and the other in 1895, which recorded the passengers on the Louther. From later publications, it is evident that Hans Yerke Hamrick, Or Hans Jerg Hamriche, or Hans Gerg Hamrick was a middle-aged man who brought his family with him. These are his family members: wife Amaryllis Eliza Hamrick; son Paul Hamrick; daughters Margaretta and Clara Hamrick; and married daughter Maria Katharine Merchant with husband Jno Ludwick Merchant and son John Yerke Merchant, who was named for his grandfather Hamrick." The above names are found in "Pennsylvania German Pioneers" by Strassburger and Hinkle. If anyone has access to the books by Annette Burgert, perhaps they would have additional information.
