The Honorable Allyn "Lyn" Nickle was elected Register of Wills in 1998 - the 16th Register elected to serve the citizens of Cecil County.

A lifelong resident of Cecil County, Lyn graduated from North East High School. She completed a course of legal studies at the National Academy for Paralegal Studies, Inc., earning an award of Scholarly Distinction. An avid student of probate law, Lyn has also completed many credit courses as well as continuing legal education classes at Cecil College, the Maryland Institute for Continuing Professional Education of Lawyers, Administering Estates in MD at the University of MD School of Law, as well as courses in Computer Systems Administration, Accounting and Mediation and Conflict Resolution. She lectures on The Importance of Having a Will and Administration of Estates at many faith-based and civic organizations and the annual Cecil County Senior Lifestyle Expo.

With special interest in preservation of the historic records, Lyn spearheaded operations to digitize old paper files and dockets. Records from the time Cecil County was established in 1674 have been imaged and preserved in digital form. In addition to the imaging system, she supported design and implementation of an Electronic Document and Records Management System, a specialized computer system, used state-wide to manage records and ensure that records are preserved and protected. The new system has revolutionized administrative practices of the office.
