The Lancaster, Pennsylvania, area is known for its Amish and Mennonite heritage. Over the course of many years, the Lancaster Mennonite Historical Society has compiled more than 210,000 index cards with records of the Mennonite families in the region. Until recently, these cards were only available to researchers at the society's library. Now, LMHS has partnered with Ancestry to digitize these cards. They are available on Ancestry as the Lancaster, Pennsylvania, Mennonite Vital Records, 1750-1940 collection. The cards were compiled from a number of sources, including family papers and diaries; cemetery records; periodicals; and county histories. Here is the card for Samuel Troop (b. 1825), his wife Sarah, and their children: Samuel and Sarah Troop and family. Lancaster, Pennsylvania, Mennonite Vital Records, 1750-1940. Note at the bottom "Israel Hollinger Diaries." That is the LMHS collection where this information came from. Those diaries are in the Personal Papers collections at the LMHS library. Many of the records are continued on the back of the card and/or are on multiple cards. Be sure to scroll through the images to make sure you've seen the entire record for that person or family.
