i have heard that one Wiley emigrated from the USA to Sonora around 1850's and 1880's. His father was irish and he never met him. He was raised by his step father who was american. Do you have any further information about him or his descendents?? Or any information about where to search for this family register, birth certificates, marriage certificates or dead certificates in Sonora??
please contact me if you know something that may be related to. thanks a lot
