Immigrant roots of my family (moms side)

I did some asking around the family and a little research on the immigrant roots of my family and this is what i came up with:

Vaclav Machart was born in Netolice, Bohemia, Czechoslovakia. He came to the U.S.A sometime between the age of 18 - 25 aboard a vessel. He landed on Galveston Island from where the horse back and wago to vicinity of Praha, Texas. Which is in Colorado, County, Texas. He worked for the railroad laying rails so he could earn money to buy farm equiptment. He married Mary J. Riha when he had enough money to buy a pair of mules and a plow. They got married at Praha, Texas. He worked a farm in that area until he bought a farm near Wied, Texas which was on the Rocky and Ponton Creek banks. He continued to farm here until he lost the farm during the depression years approximately 1940. He then continued to farm near Sweet Home Texas until he retired and moved to Charlottenburg, where Mary's life ended.  Vaclav died at his sons home near Shiner, Texas. The reason he left Czechoslovakia was that Austria, who was controlling the government of Czechoslovakia, was drafting all young men into their army so he defected to the U.S. He had to wear a disguise in order to elude the Austrian government. He left from Bremnan, Germany for the USA.

I couldnt find the approximate dates, although i know by other information, that the dates start some where between the mid or late 1800s. My mom used to be a Machart before she married and changed her last name to Clark, so that is how it is apart of my family history.
