My vote was  for "I don't really have an opinion on this." but after I voted I googled forty fathoms just to see what came up and with that knowledge a name change does not sound so bad. I also google Sarah Christina, its a name, other people with similar names showed up, the image preview was of what appeared to be your art. I also found what I hope is your artstation page. 
Having a good across the board name, something that could double as a brand would be best. Whatever it is should be unique and fits you and your needs. I could be wrong about Forty-Fathoms but seeing a skin care product with same name at the top of google was a bit blah, I know you do not have control over that . Your deviant art did show up top 10 for me with Forty Fathoms as the search so that is not bad.
The more I google the more I think your are at a good spot and I just wasted some time lol all good, going to keep the above thoughts down. your deviant art both show up top 10 for both forty fathoms and Sarah Christina for me and that is great. Do to the change that deviantart is about to make to urls I would wait and see if it changes your rank in google at all.

FYI SarahChristina is currently deactivated account I know you said "such as" you may be about to get not sure how that works. You can see what was once there over on web.archive.org/web/2012111503… that is from 2012 you can go back more.
lol that was about an hour and a half I will not get back but you know what I do not see it as a wast lol other may. 
What ever you decide I wish you the best.
