According to one source, "Catharina Funk (1741-1806) ... was the daughter of Johannes Funk and Sibilla Miller. When her father died, and the mother remarried, Catharina became an orphan and at the age of ten years was apprenticed to a local tavern keeper" until she was 18. (Frank Wilson Kiel, Hendrik Gerrit Kiel -- Dutch Immigrant to Pennsylvania, Comfort, Texas: Skyline Ranch Press, 2000, page 36, citing York County, Orphans Court, Apprenticeship of Catherine Funk to Michael Swope, 1751, Pennsylvania State Archives.)
From Eleanor Wicks' Research:
"The following note was in a box of papers: " The Departure of My Dear Mother Jan 11th 1806" with the word "Mother" written on the side of fold. Content inside the note: "January the Eleventh eighteen Hundred and Six This day our Deer Mother Departed this Life about Twenty minits after Four O Clock in the after Noon." It appears to have been written by her son, Joseph; comparison to handwriting in his business ledger shows similar formation of many letters.
December of 1982, the home of Marguerite Barnett, 2x granddaughter of Catherine Funk Kern, was broken into and stripped of antiques and family papers. Only a few remained; this had been photocopied about three years earlier."
This date harmonizes with census records and tax records for Catherine and her son Joseph Kern. Catherine was in her son Joseph's household in 1800 (1800 Census York County, York Boro, Series M32, Roll 44, Page 1294). Joseph is said to be on the York tax rolls until 1805 (Ed Morrill, "In Reply to: KERN family of York Co., PA ," posted at rootsweb.com York County message board on 30 Nov 2003.) and Joseph is in Westmoreland County by 1808 (Tax Lists, Westmoreland County, PA, 1786-1810, edited by William Dumont, Washington, DC: National Genealogical Society, Special Publication No. 33, 1968). Joseph's 1810 household has no female old enough to be his mother (1810 Census: Westmoreland Co., Greensburg Borough, Series M252 Roll 51 Page 183.)
