Unfortunately it is not enough information to find your husbend's ancestors. There are 4 Janovice villages in the Northern Moravia, so I hope that you mean Janovice in Frýdek-Místek county. Volný, Carbol, Žídek are very common surnames there (413 of Volný/Volná, 224 of Carbol/Carbolová, 157 of Žídek/Žídková in county Frýdek-Místek in 2010). The online parish books of Janovice belonged to Skalice parish, see http://matriky.archives.cz/matriky_lite/
and description in the Kbeqgen's post above. Newer parish books are not digitized and they are deposited in the register office in Frýdlant n.O., http://www.frydlantno.cz
Now it is question how much information about husbend's ancestor you have, such as birth, marriage or death certificates (or passanger lists at least).
