John H. Huy is, I believe, the son of Henry and Mary Huy of Nevada County, CA. John Sr. was b. 1838--PA and Mary was b. abt. 1850 in Louisiana. Their first son John H. Huy was born in March 1874, probably in Nevada County. My current research incidental to this line shows he had several brothers:
Joseph E. Huy--b. 1876
James Leo Huy--b. 1886
Jacob Huy--b. 1873
George W. Huy--b. 1883
Huy is a surname found in both Germany and France. More info available.
