I have a small calling card (business card) dated prob. 1880's. There is a tine picture of a gentleman along with the name H.J. Coller. Is this another variation of Koller. My ggrandfather Peter Jonas Johnson's sister married a Koller as well as my ggranmother's sister also married a Koller. I'm thinking perhaps the spelling was passed down wrong for one of the spouses. Any suggestions or help on the name Coller would be appreciated! Brenda Johnson Gaetz.
