This database contains records of Maryland declarations of intention, petitions for naturalization, oaths of allegiance, and occasionally supporting documents such as certificates of arrival (NARA Film M1640). These records can be searched by the immigrant’s birth year, immigration year, and by his or her name. We also allow an additional search for witnesses, just to provide some additional match possibilities. The best results are often obtained by typing a full name into the search box directly below. Some records are labeled by immigration year, which is why some dates occur before the 1906–1930 time frame for this publication.
