The marriage Index for Maryland, from 1655 to 1850, is a valuable resource that features an organized list of about 258,000 individuals who tied the knot during that time frame. However, records from Calvert County are unavailable due to a courthouse fire in 1882, which destroyed most documents. Furthermore, the index does not cover Garrett, Howard, and Wicomico counties since they were established after 1850. It’s important to note that the indexed records may not be exhaustive for the particular time and area covered.
