Daniel Byrd
Daniel "Danny" Byrd was a Human born in the mid-24th century, who lived in the Federation colony on Kessik IV. 

As a child, Byrd attended grammar school with B'Elanna Torres, where he often terrorized her. He used to point at her cranial ridges and tease her about being half-Klingon, calling her "Miss Turtlehead". This would anger Torres until one day during recess she attacked Byrd while he was on the gyro-swing. Torres disengaged the centrifugal governor, which caused Byrd to spin so fast that he almost flew apart. Torres then yanked Byrd off the swing and started hitting his face until their teacher, Miss , showed up to stop her. ()

Byrd later attended Starfleet Academy and became best friends with Harry Kim. They graduated from the Academy together on stardate 47918. ()

In an alternate timeline Ensign Byrd was assigned to duty aboard the , where he was assigned as operations officer, in place of Kim. Shortly thereafter, on stardate 48307.5, Starfleet lost contact with Voyager, which had been lost in the Delta Quadrant. In this timeline, Starfleet had a memorial service for Byrd and the rest of the Voyager crew, two months ago prior to stardate 49009.9. ()
