Thank you, Richard.
Sorry I have been so long in replying, but the system of notifying me seems to have been lost. I just got back to this message board today. My apologies again.
You did not give me your e-mail address, so here is mine (or rather my husband's): email@example.com
I have found my great grand-father in the Sac. Co., 1880 census, but the spelling was Olohusin as I interpreted it from very hard-to-read handwriting.
Thank you again for your help.
