Onella and her "daughters"
Onella, "the Mother", was a star named by Iko when he was a child. From his vantage point, she was surrounded by sixteen smaller ones, her "daughters", which Iko had named as well.
In 2376, Iko discussed his memories of Onella with Seven of Nine, who later located the star and showed images of it to Iko in the astrometrics laboratory on the USS Voyager. (VOY: "Repentance")
