Nancy Pelosi was Nancy D'Alesandro from Baltimore Maryland. Both her father and brother were mayors of Baltimore. Her Father Thomas Jr. was mayor from 1947 - 59 and was a congressman before that from 1939 - 47. Her brother was mayor from 1967 - 71.
Nothing juicy but hope it helps.

(we see the old democratic dirty tricks)
Politics consumed the Baltimore leader, so much so that his closest lieutenant described meetings at his party club as "political science lectures." Although a strong supporter of FDR and progressive Democrats, Pollack's interest was not in public policy, but in political power itself. The key to this power was commonplace: handouts and intervention with the government for the poor, patronage distributed to election workers in keeping with their achievements in winning votes, payoffs from businesses that wanted city contracts and favors, retribution for those who opposed him. Pollack established a frightening reputation for vindictiveness. "When you really got Jack angry and he wanted to dismiss you," his closest associate reported, "he would say goodby to you by saying, 'Good luck and best wishes.' It was like he was sitting Shiva."
By the 1950s, Pollack began to lose his voter base, as Jews and other whites took flight from Baltimore, and blacks rose in number, eventually becoming a majority of the city's population. A series of electoral battles ensued, with the first black success coming in 1954, as a young lawyer Harry A. Cole defeated the Pollack machine to become Maryland's first's black state senator. Pollack grudgingly tried to accommodate, slating a small number of receptive black candidates along with predominantly Jewish candidates, while challenging new voters and bringing white voters to the polls in Baltimore even after they had moved to the suburbs. The population tides eventually could not be held back; by the 1960s blacks leaders and machines replaced Pollock and took control of Baltimore's party organization and the city government.
