That is them, i have Evan and his brother Edward living in a boarding house in 1882 in Leadville and my great grandmother living with her first husband 200 mertre away (he was killed in an accident) i have then found Evan Christian was heavily involved in forming a break away union that caused a strike in Leadville Colorado, than caused a lot of deaths, and required the govenor to bring the troops in, it lasted 18 months, he had some sort of a back ground, his son was called William, daughter was Mary, who called her first daughter Mona, (passed away last week at 95) i believe Mona has some connection to Isle Of Man was once referred to as Mona's Isle (but it actually means mountain) so i am told.
Hope this all makes sense.
