Hello.. I am looking for any information on YSAIS ESPINOSA (my Gr Grandfather) or any of his family. I only know that he was born in 1891 and died in 1970. At the time of his death he was living @ Neenah, Winnebago, WI 54952. I was told he was full blood Chippewa Indian and was born on the reservation. I have no known facts other than birth death. Any help would be appreciated!
