After reading my posting regarding the Sarah Coates/Penrose/Faulkner/Dutton an interested list member contacted me regarding information listed in their records that differed by one year when compared to the date I was listing. This resulted in a bit of research and additional discoveries that might interest someone else on the list so I am sharing a portion of the correspondence.... ----------------------- "So I'm not sure what is causing the years difference in the books - perhaps it is a printing error in one of the publications. But more likely it was caused by the change from the Julian Calendar to the Gregorian Calendar. Here are several sites that explain it better than I can since it always adds to my confusion... http://www.crowl.org/Lawrence/time/britgreg.html http://www.genealogytoday.com/columns/recipes/tip14.html http://www.genfair.com/dates.htm http://homepages.rootsweb.com/~hornbeck/misc.htm I did notice the same one year difference between Thomas Penrose's Tombstone Inscription in Christ Church Cemetery (on Ancestry.com) which listed his death as November 17, 1758 (aged 48 yrs) but in Philadelphia Wills (on Ancestry.com) his will was written 11/8/1757 and proved 12/22/1757. In the actual book covering Records of Christ Church - Thomas Penrose is shown with a date of death of November 17, 1757. Another oddity listed in the online Tombstone Inscriptions is that it appears that buried with Thomas Penrose is "Sarah his wife who departed this life July 7th 1777 aged 63 years and 3 months" (even though she married twice after his death). I think our downfall is having to rely on transcriptions offered by other's who are able to visit the sites offering original documentation but with the calendar change during certain periods even original documentation is subject to adjustment." -----------------------------
