If you have photos not claimed by specific families which you would like to send to a good home, may I suggest the the Merrick County Historical Museum and the corresponding group in Howard County, which I do not know the name of.
I am the treasurer of the Merrick County Historical Museum Inc., a nonprofit group run by volunteers. Our mission is to tell the continuing story of the people of the Merrick County area. We often respond to queries from people with Merrick County ancestors and often share copies of old photos in our collection with them.
You can contact me via e-mail or send snail mail to: Merrick County Historical Museum Inc. 211 E Street Central City, NE 68826
