Paca has been described as being of
Italian ancestry from
Abruzzo. According to Stanley South, "[t]he rumor that the name was Italian came from a remark made in 1911 by
James Cardinal Gibbons of Baltimore, who commented that he thought a relationship existed between Paca and the Italian family Pecci". In a July 18, 1937, letter to the
New York Times, a self-described descendant of Paca claimed:The ancestors of William Paca were of
Italian and
English origin. The name is said to have originally been spelled Pacci [sic]. However, in an interview with Giovanni Schiavo, the letter writer apparently attributed the suggestion that the name was Pecci to Cardinal Gibbons. Schiavo also reported that Paca mentioned
Pope Leo XIII, whose surname was Pecci, during the interview. Neither "Pecci" nor "Pacci" (nor "Pacca") are attested, but that could be attributed to the fact that the Italian spelling of the name would have simply been difficult or unfamiliar to the English-speaking clerks of the time. If the Paca family did have
Anglo-Italian origins, they were distant. William Paca's father John Paca was born in
Colonial Maryland, as was his grandfather Aquila Paca (). His great-grandfather Robert Paca was born in
England in 1632, arrived in Maryland by 1651 and may also have gone by the surname "Peaker." ==See also==
