Dominique Name Origin

From the Japanese Wikipedia:

The youngest of the late Nelson Royal’s three daughters (in the movie version, the second; in the TV version, the eldest). She meets COBRA looking for Nelson’s hidden treasure. In her first appearance she’s ostensibly a member of Snow Gorilla, an organization subordinate to the pirate guild that killed Jane and Catherine.* However, in reality she’s an undercover Space Patrol officer (referred this first time as Lt. Nelson, which is corrected in later installments**), and will fight alongside COBRA on multiple occasions.　She is faithful to her job as a Captain in the Space Patrol,*** but has no qualms about enjoying her time off, sometimes going on vacation/holiday with COBRA. Eventually she is killed by Salamander and his underlings, with COBRA finding only the skin fragment from her back with her tattoo as proof. Upon seeing it, COBRA mourns her deeply, shedding tears for the first time in the series. When he defeats Dober, COBRA swears revenge against Salamander, crying “I shall not rest until I’ve found you, and used these very hands to crush you to pieces!” Afterwards, a Space Patrol officer identical to her named “Secret Sanders” appears, but the reasons for their resemblance and the two's relationship remain a mystery. Additionally, while she’s considered to be “dead” in the series, her dead body is never seen save for the skin with her tattoo, nor is her actual death in any way shown, so that fans may take the interpretation that she is still alive. The TV series took this one step further, where she is shown to be the founder for the Church of Millar, her memories having been altered. In the movie, she has wavy long hair, giving her an appearance that is distinct from the TV series and original manga.
