Martin served in Captain James Young's Militia Company with his brothers John George and Jacob and his brother-in-law, John Ralphsnider.

Martin was the administrator of his brother Jacob's estate in 1791 and of his father's estate in 1790. During November of 1792, Martin sold his Pennsylvania land and cleared all legal encumbrances, presumably to move to Greene County, Tennessee. Many residents of Franklin County, including Froschauers, also settled in Greene County, Tennessee. Martin appears in the Greene County Court Minutes in 1796, and on the Greene county tax list having "no land, 2 white polls, and 2 stud horses" for 1797, but his name is missing from all such records thereafter. Where he went or what happened to him is unknown.

   Martin Cook married Catherine ___ some time before 1792. During November of that year Martin sold his Pennsylvania land and cleared all legal encumbrances, presumable to move to Greene Co., TN. He appears in the Greene County court minutes in 1796, and on the Greene County tax list having "no land, 2 white polls, and 2 stud horses" for 1797, but his name is missing from all such records thereafter.

   8. Several of Catharina Koch Froschauer's in-laws are listed on the Greene Co. TN tax list for 1798 with large acreages, showing that Martin Cook was not the only Franklin Countian who moved there.
