I am the owner of bitcoin firstbits 1GLENCo.
Apparently I created multiple stacker.news accounts somehow and have not yet figured out how to unfuck that, so this account's nym is set to 1GLENCoo. I have yet to figure out how I created the 1GLENCo nym. :-/
FWIW, I am the owner of all of the following bitcoin firstbits:
1GLENCo (https://mempool.space/address/1GLENCoSJJHH7FahyhTi16iwZQcHtMbxA4),
1GLENCoo (https://mempool.space/address/1GLENCoo58vDpnVAiBHSPbmBQhTQzSMyTh),
and 1GLENCoop (https://mempool.space/address/1GLENCoopvTFq7ZxvJPhrvk8nPbZxbU3hx).
