Siler, A. O., compiler. The Siler Family: a Compilation of Biographical and Historical Sketches Relating to the Descendants of Plikard Dederic And Elizabeth Siler. (Marfork, W. Va.: the Author). 1922.
The couple referenced in the title was, apparently, part of the Palatine immigration wave of the mid–1700s. They arrived, according to the compiler, before 1745, when their first child was born in Pennsylvania. The compiler makes few hard references to Plikard and Elizabeth Siler, so the reader is left in doubt about their heritage. The book is almost completely devoid of source citations and references thereto. There are many blanks for descendants to fill in and otherwise complete the information missing from the printed copy. A number of family meetings and reunions are discussed as well, some dating back to the mid–1800s.
The Siler Family really begins with Philip Siler, Senior, born 5 May 1745 in Pennsylvania, and carries on through his descendants. Shortly after arriving in the colonies, the family migrated south to Virginia and then North Carolina. From there, the family migrated westward to states such as Kentucky and Tennessee.
The Pacific Northwest connection appears at page 69 with Rufus Theodore Siler, who was born 11 April 1863, at Franklin, North Carolina, and married Josephine Landes, 3 December 1886, at Mossy Rock, Washington Territory.
Two sons of Thomas Summerfield Siler (b. 19 April 1834, d. 6 April 1916) and Louise Herren, (d. 25 January 1903) also migrated to Washington Territory in 1886: Judson Sawin Siler (b. 14 June 1863) and Alfred Weimar Siler (b. 31 May 1868). Both settled in Vance. (pp. 70, 72)
Three sons of James M. Siler, of Kentucky, moved to eastern Washington in the late 1800s: S. Boyd, Joseph, and Elisha. Geo. W. Siler, son of William H., also moved to Washington about that time. (pp. 158–159)
Several daughters married men who later migrated to the Pacific Northwest. One Oregon resident is also mentioned.
This volume includes a preface filled with generalities and patriotism. A four-generation chart, spread over a number of pages, also devoid of source citations, begins the text. There is a surname–given name index at the end.
The Siler genealogy is available on Google Books. It is a free download, as it in the public domain. The copy used here was from the Wisconsin Historical Society collection.
