The O'Brien family moved from Lock Haven, PA to Douglas County sometime between 1860-1870.
Ellen (Connolloy) and Patrick O'Brien and several of their seven children (Thomas, William, James, Patrick Jr., Elizabeth, Catherine, Mary & Agnes), all moved. William was my gggrandfather and married Clara Manhart of Sedalia.
It appears that Patrick (b. 1824? in Ire.) died sometime between 1880-1885 in Douglas County.
Ellen (b. 1829? in Ire) is last listed as residing in Pueblo in 1900 with her sons James and Patrick Jr. and daugthers Agnes and Mary.
If anyone could look up Ellen's or Patrick's obituary or provide any insight into the O'Brien family(ies) living in central CO 1865-1930 I would be VERY appreciative!! Thanks
