There is a some information on this family and the various relatives on the www.familysearch.org site. There must be some LDS connection based on the Manassa, Conejos, Colorado connection and information on the mentioned website. I have folks with the Birdno name in my family tree and have been to the two Manassa cemeteries in the past. I can go again as it is not that far to travel. If I can be of any assistance, please let me know.
