Either Jennie is fibbing about her age, or her mother is inflating hers, or both, because it is virtually impossible for any woman to birth a child at the age of 47.

JOSHUA MARSH CORBIN.  For the greater part of half a century Joshua Marsh Corbin has been diligently employed in his profession as a civil enginner, and most of that time his headquarters have been in Lexington.  He is the present county surveyor of Fayette County, and altogether his official association with that office covers twenty years. Mr. Corbin was born in Bourbon County, Kentucky, a son of Joshua and Rachel (Marsh) Corbin.  His parents were also natives of Kentucky and of Bourbon County.  His father was born in 1800 and died in 1869, and his mother died in 1887, at the age of seventy.  Of their seven children, Joshua M. is the only survivor, and he was next to the youngest.  His father was a farmer, and like many Kentucky gentlemen was distinguished by a love of fine horses and high-class cattle.  During the Civil war period he was a stanch Union man, but in politics usually voted independent. Joshua Marsh Corbin acquired a public school education, and attended Professor Clark's High School at Paris, Kentucky, and took the scientific course of Center College at Danville.  It was in 1871 that he received his first important promotion in his profession, when he was made assistant city engineer of Lexington.  Later he was engaged in the practice of architecture with P. L. Lundon, under the firm name of Lundon & Corbin.  In 1878 Mr Corbin was first elected county surveyor, and he held that office consecutively for sixteen years.  For eight years of that time he also acted as city engineer of Lexington.  In 1896 he was appointed by John G. Carlisle, then secretary of the treasury, as assistant superintendent of construction of United States Life Saving Stations, and he performed the duties of that office for about two years.  In that connection his duties involved a great deal of travel.  He then practiced as a civil engineer, and in 1918 was again elected county surveyor of Fayette County.  Mr. Corbin is an active democrat in politics. In 1876 he married Jennie Lyle Cook, a native of Lexington and daughter of Mr. and Mrs. John Cook, who are now deceased.  Mrs. Corbin was the youngest in a family of two daughters and five sons.  She and Mr. Corbin have five children:  Ina, Nathan Marsh, Margaret (wife of Walter Caspe), Burnie B. and Chester C.
