I believe the reference to Gano's Squadron may have come from the fact that the Compiled Service Records at the National Archives are found on the same microfilm roll as that of Crump's/Lane's Texas Cavalry

M323: Compiled Service Records of Confederate Soldiers Who Served in Organizations from the state of Texas

Roll 192 Crump's Cavalry (Lane's Cavalry, 1st Partisan Rangers)
Frontier Battalion, Cavalry
Gano's Squadron Cavalry

Gano’s Squadron Texas Cavalry consisted of two companies, A and B, which had been organized March 6, 1862, for twelve months. It was assigned to the 7th Regiment Kentucky Cavalry sometime during the summer of 1862, and became Companies A and B of that regiment
