Jacobus was born on 3 October 1887 in New Haven, Connecticut, the only child of John Ira Jacobus (1855-1912), a banker,[2] and Ida Wilmot Lines (1855-1952), daughter of Henry Lines. The Jacobus family's lineage can be traced back to Dutch origins, recorded in Albany, New York, in 1683.[3][4][5]
Jacobus began working on his genealogical compendium Families of Ancient New Haven in 1912, and it was published in eight volumes between 1922 and 1932.[1] This compendium was published as a part of The American Genealogist journal (originally called New Haven Genealogical Magazine), which Jacobus established in 1922. He served as editor and publisher of the journal until 1937.[6]
