How can I obtain a copy of the 1900 Federal Census for Green wood County, Kansas. I think it is Otter Creek Township.

I am looking for data on my Grandfather George Moser and his wife Ruhanna Spring. They had several children during the 1900 census. They had another daughter at a later date.

Could you tell me what the cost would be to have a copy of the Moser Family taken during the 1900 census?
