A Connecticut family of six and a pair of Houston-area sisters have been killed in the Dana Air plane crash in Lagos, Nigeria that killed all 153 on board.

Maimuna Anyene, her four young children, her mother and her husband, Onyeke, of West Hartford, Connecticut, were on their way to a family wedding in Nigeria at the time of the crash, West Hartford Patch reports. Maimuna lived in West Hartford while her husband lived in Nigeria, the Hartford Courant reported.

A neighbor told Patch: "I knew her as a neighbor, from being out playing with the kids...They were going to be moving, and that alone devastated the neighborhood. Six people gone – it just doesn't make sense," she said.

Also on the plane were Jennifer and Josephine Onita, sisters from the Houston-area who were also on their way to a wedding, the Houston Chronicle reports. They are the middle children of pastors, whose church is affiliated with the Nigeria-based Redeemed Christian Church of God, according to the Houston Chronicle.

Officials said Monday that the pilot of the Dana Air plane was American, though his name and hometown were not released, according to CNN.

State Department spokesman Mark Toner said Monday that the department believes there were many Americans on board, but could not pinpoint an exact number, adding: "We're still, frankly, unable to provide a firm number. I can also say that our consulate in Lagos is working both to notify the next of kin and also provide any appropriate consular assistance."

The Guardian reports that the Dana Air craft was 22 years old. Nigeria, however, has a ban on aircraft over 20 years old, according to Fox News.
