online identity

I am considering doing a race for which I would have to agree to open a fundraising web page and let my photo be used with folks from the charity. This gives me pause, because I try to keep myself at least somewhat private online. Even so, I feel like I really am all over the web (DW, twitter, Instagram, member of various chat lists), but after a google search and a duckduckgo search, I am a bemused by the results. Since voter registration and property taxes are public documents, I'm not surprised to see my name and address linked, but others are more mysterious. I have rung dozens (more) of quarter peals. Maybe half a dozen show up. I spent a couple of years writing a column for the local weekly newspaper. Nothing, although my dean's list and graduation notes from UMass Lowell are there. I have run many races in various places, the times of which tend to be online on sites like coolrunning. Only a few show up. I got a hit from an obituary in 2009, because I had written a one-line condolence message. I got a few things from church or charity newsletters. I have a common name - one of the snoopy sites claimed to have 125 people with my name. I didn't know that there had been someone with my name working for the BPD, but I did previously know about the real estate agent in Lexington, KY. This commonality means that many genealogy sites have what looks like my name, but only a couple of them seem to actually be me. I am linked to Arthur in a few places, including his academic web page. In some ways, the weirdest thing is the listing for a person with my name plus an added middle initial H. I get donation requests for her, and always assumed this was a typo from some organization. I remember the story of someone who could track which charity had sold or exchanged her name, because it was the one that spelled Eve as Eeeeeve. L. H. is listed on Intellius and others at our address, with our landline number, and my age. I don't know what to think of the online presence of typo lady, or whether I should try to get rid of her.
