THOMAS McGUIRE

     a substantial and representative citizen of Sumpter, has for the past four
years represented the Columbia Gold Mining Company as superintendent of the
Columbia mine. His birth occurred in County Roscommon, Ireland, on the 9th of
November, 1863, his parents being John and Katharine (Breheny) McGuire, who
spent their entire lives in Oat county. The father was a stone mason by trade.
     Thomas McGuire, who was the second oldest in a family of thirteen children,
remained under the parental roof until nineteen years of age and then went to
the Bell quarry in Scotland, working in the limestone mines there for three
years. In December, 1885, he crossed the Atlantic to the United States and
arrived in Portland, Oregon, in January, 1886. He was accompanied by his sister
Maggie, who is now the wife of Michael Welch, of Dole, Washington. Making his
way to Baker City, Mr. McGuire worked in quarries during the first summer and
during the next summer worked at railroading, being employed on the construction
of the Cascade tunnel. After returning to Baker City he worked with stone masons
and in 1888 became a member of the police force, acting as chief of police
during the last three years of his connection therewith, which terminated in
1894. Subsequently he spent about four and a half years at the Bonanza mine and
later did work in connection with other mines. In December, 1901, he entered the
service of the Columbia Gold Mining Company as shift boss, while for the past
four years he has held the responsible position of foreman at the Columbia mine.
In this capacity his previous experience has served him well, enabling him to
wisely direct the labors of those under him.
     In 1907 Mr. McGuire was united in marriage to Miss Ann Keaveny, who was
born in County Roscommon, Ireland, in 1862, and came to the United States as a
young lady, settling in New Hampshire. The marriage ceremony was performed at
Sumpter, Oregon, by Father Welch. Mr. McGuire gives his political allegiance to
the republican party and in religious faith is a Catholic. Fraternally he is
identified with the Benevolent Protective Order of Elks.
