I am looking for information on John McDermott born 1849 in Michigan, United States. He married Cordelia Keene. Through census records I have traced them to Texas, Iowa, Missouri and Colorado where the family was in San Miguel and Pueblo Colorado. His parents were immigrants and are from Ireland or Scotland (there is disagreement on the census records which it is). I can find no information on any siblings.
Know who John's parents are?
If he has any siblings?
Have any documentation of his birth, death, or marriage?
Any help would be appreciated. I can share any info I have gathered on this family although it isn't much and is mostly from Colorado.
