They had four children, one of whom, Maria Louisa Gitt, married William Gardner Smyser (1845-1926),[4] a civil engineer for the Santa Fe Railway living in Topeka, Kansas.

[12] Gitt in his report notes that he conducted reconnaissance and instrumental surveys for the road and had located the route from Union Bridge to (permanently to the Monocacy) Thurmont, east of the mountain, and from Mount Zion (permanently from Chewsville) to Hagerstown, west of the mountain as well as proposed branches to Emmittsburg, and up Friends' Creek to Mount Zion.

[15] Gitt developed the cost estimate for the road assuming single track operation, iron rail at 52 pounds per yard, ties on 24-inch centers, a road bed base fourteen feet in width, with slopes of one foot and-a-half horizontal to each vertical for cuts or fills.

A second route started on the east-side and headed due north to Worman's mill and intercept the first line near the river crossing.

Gitt then briefly became chief engineer for the European and North American Railway from Bangor, Maine to New Brunswick, Canada for the extension from Saint John westward.

On January 22, 1901, Gitt died in New Oxford, Adams County, Pennsylvania and was buried at Mount Olivet Cemetery in Hanover with the rites of the Odd Fellows.

[21] Gitt estimated that in his career, he had conducted 31 different railroad surveys for a total distance of over 300 miles in his career [22] Gitt either surveyed or engineered most of the railroads constructed in Frederick and Carroll county, Maryland and Adams county, Pennsylvania in the 1855-1885 period with the exception of the Civil War.
