There is an Elizabeth Shimmin will in 1823 on film 0106423 and German burials on Sept 20 1818 and June 18 1826.
Also rightly or wrongly, the IGI has an ancestral file for Elizabeth the daughter of John Shimmin and Ann Quirk. This shows her marrying Henry Clucas. However I found no parish transcription or census data (I have not looked at 1841) to support this. The IGI has another Elizabeth born to John Shimmin and Mary Kelly in German in January 1798.
