One notable Eymann/Iman family member was Cornelius Iman of Grant & Hardy County, West Virginia. Cornelius was a gunsmith in the mid-1800s. You can find his genealogical setting in the tree here: http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?op=GET&db=teymann&id=I6704, and some biographical information here: http://hampshirecountylongrifles.blogspot.com/2013/11/cornelius-iman-gunsmith-grant-county.html.
Family member Kim Conner wrote today at the Iman forum (September 8, 2014): "...my first cousin has one of his rifles that she inherited from her father. She needs to sell it due to financial hardship after being diagnosed with multiple sclerosis and I’m handling that for her. We’d like to see it stay in our immediate family or go to another Iman descendant, but we also need to raise as much money as possible for her, so we believe the fairest thing to do is an online auction to give everyone a chance to bid on it. The auction will be probably be in the first week of October and I’ll post the details here. I’ll probably be using gunbroker.com. Feel free to contact me at email@example.com with any questions."
