My IRL name is ridiculously common, and there are also three noteworthily successful people with my name. However, I can do a Google search that returns mostly references exclusive to me by adding facts about me that, while not unique, narrow it down substantially.
For example, if I wanted to generate hits only about me and not others with my name, I would use Google Advanced and type “Cairo Carol” in the exact word/phrase field, plus a lot of biographically relevant words in the “all these words” and/or the “any of these words” fields. If I type my college, the town where I graduated from high school, two or three of the countries I have lived in, and/or the name of past employer(s), Google is reasonably good about returning hits that relate to me.
It’s not perfect - the three other “CairoCarols” that collectively have a ton of internet presence include a BBC newscaster, a world-traveling photographer, and an academic in the area of Indonesian dance. But if you KNOW that, you can add terms to the “none of these words” field like - in my case - “BBC,” “photographer,” and “dancer.”
It can also be useful to use the same search strategies on Google Images, then scan the pics. A lot of times you can spot a photo of someone or something that you know is relevant to the person you are researching. Click on the photo and see what is on the site it came from.
Finally, to expand a little on the excellent suggestion of including “obituary” in searches that you do - she may still be alive, but probably a parent or other close relative has passed away. Her name will appear as someone who survived them, perhaps as “Van Tower of Duluth, Mn” or some such. That may help you narrow down your search/give you new clues to use.
Incidentally, I’m not a stalker, though I feel as though I may be giving the impression that I am. (And if I wanted to stalk, I bet I’d be above average in my use of internet tools to do so.) The reason I have moderately above-average Googlefu is experience: I worked for a publisher of news and general interest magazines circa 2002-2008, when search engines were just developing into useful tools. There is nothing like working in the newsroom at midnight, needing to get layout to the printer in three hours and some fact-checking concerns about the articles you’re reading, to hone your use of Google to answer last-minute questions.
