Colonial

Few naturalizations were required in the colonial period since most immigrants came from the British Isles. The legislature and the Governor and Council naturalized some foreigners, but most persons were naturalized in the later colonial period under a 1740 Act of Parliament.

The Maryland State Archives has several indexes to colonial naturalizations found in Provincial and General Court, General Assembly, and Governor and Council records of 1634 to 1776. Naturalizations of colonial German immigrants, including lists previously published in the Archives of Maryland (see the “Public Records” section of this outline), are in:

Wyand, Jeffrey A., and Florence L. Wyand, Colonial Maryland Naturalizations. Baltimore: Genealogical Publishing Company, 1975. (FHL book 975.2 W5w; computer number 261707.) This source may include religion, birth date and place, death date and place, or residence.

Post-1790

After 1790 under federal naturalization law, aliens could declare intention to become citizens and later be naturalized in any federal, county, or city court. The Family History Library does not have copies of these court records.

The Maryland State Archives has most county naturalization records, indexes to many county records from 1778 to 1906, and indexes to Baltimore city and county naturalizations from 1793 to 1933. The archives also has a card index to naturalizations in the U.S. circuit and district courts from 1797 to 1951.

You can find abstracts of naturalization records in:
