Perhaps you may be willing to look for the following arrivals during 1880-1884 at Castle Rock. OLE BENARD BOGERSEN; dob. 1861. He may have with him his wife (if married in Norway) ELISE, dob. abt 1847 and her daughter MARTHA. 1900 federal census shows him coming in 1884, however, other records seem to point to earlier years of 1881, 82, or 83. Abephew, MARTIN BORGERSEN, may have travelled with him also, or aat a different date within the same time period. What disks do you own? May I ask where I might purchase these? Thankks alot. Karen
