JOHN C. BRENNAN.  Another of the sterling sons of the old Empire state who has 
come to Walworth county and here found a pleasant home and a welcome from our 
citizens, and thereby has benefited himself and them, is John C. BRENNAN, a 
successful farmer of Linn township.  He was born in Chenango county, New York, 
March 2, 1865, and he is the son of John and Bridget (QUINN) BRENNAN.  His 
boyhood was spent on his father's farm in New York.  Upon reaching manhood he 
came west and located in Linn township, this county, and has lived here ever 
since.  In his boyhood he worked out for several years.  About 1894 he began 
farming for himself and in 1903 he purchased the farm which he still owns in 
Linn township, sections 23 and 24.  His place consists of two hundred and 
eighteen acres of excellent land which he has placed under splendid 
improvements and a high state of cultivation, and here he carries on general 
farming and stock raising on an extensive scale.
 
Mr. BRENNAN was married in 1893 to Anna BARLOW, daughter of Edward and 
Margaret (CREIGHTON) BARLOW, the father born in Linn township, this county, 
November 11, 1842, being the son of John and Catherine (SMITH) BARLOW.  John 
BARLOW and wife were both born in Ireland, and they emigrated to Walworth 
county, Wisconsin, in an early day, being among the first settlers of Linn 
township.  Edward BARLOW grew to manhood here and farmed most of his life. He 
married Margaret CREIGHTON, daughter of Peter and Ann CREIGHTON.  She was born 
near Providence, Massachusetts.  Her parents were also from Ireland, coming 
here probably in 1843, spending the rest of their lives in this county.  Mr. 
CREIGHTON bought a farm in section 5, what is now the DILLENBECK farm, and 
there he lived until late in life, then sold out and moved to Lyons, where he 
and his wife spent their last days.
 
Four children were born to Mr. and Mrs. BARLOW: Anna, who married John 
BRENNAN, subject of this sketch; Katie, who died when about twenty-four years 
of age; Lillian is the wife of John MURPHY, of Linn township; John, who is 
farming in the east side of Linn township; Edward died on December 28, 1908.  
Mr. and Mrs. BRENNAN have one son, George.
 
Mr. BRENNAN has been a member of the board of supervisors for about thirteen 
years, filling this office to the satisfaction of all concerned, and he has 
been a member of the county board for about eight years.  He and his family 
belong to the Catholic church.
