Pierre Le Moyne d'Iberville wrote that in the year 1650 the population of both the Acolapissa and Tangipahoa combined consisted of 250 families and around 150 men.
However the research by James Mooney determined that a more accurate count was proposed by Jean-Baptiste Bénard de la Harpe when he found that the tribe population was around 1500 people.
[3] On March 31, 1682 Henri de Tonti on a journey with René-Robert Cavelier, Sieur de La Salle wrote that they camped at Maheoula, a Tangipahoa settlement.
La Salle wrote that when he asked the Bayogoula tribe what had happened they claimed that the Tangipahoa village was destroyed by the Houma people.
[5] The remaining Tangipahoa tribe members are believed to have reunited with the Acolapissa and eventually merged with the Bayogoula and then the Houma.
