JANES & MACKEN surnames

Hello from Minnesota!  I am searching for JANES and MACKEN. I have searched high and low in the U.S. for any information which will show where in Ireland my ancestors came from, but to no avail. Since JANES is not a common surname I decided to see if I could find them in close proximity in Ireland...

Francis JANES b abt 1822 married Mary Jane MACKEN who was born abt 1825. They married abt 1845.They emigrated to U.S. around 1850, settled in Staten Island in N.Y.C.  Had daughter Mary Jane abt 1847, possibly in Ireland. In the U.S. they attended an Episcopalian church. Francis JANES' burial record from 1885 says his father's name was also Francis and his mother was Fanny. Mary Jane MACKEN's parents were John and Margaret.

I have searched Griffith's and the Tithe applottment records for JANES and MACKEN (and variant spellings of both surnames including McCann). JANES are non-existent in Griffith's Valuation but JANES and MACKENs both appear in the Tithe Applottment in County Clare.

James JANES appears in Townland of Mlooneen in Dysert Parish in 1843

Michael MACKEN appears in Townland of Dromcavin in Dysert Parish in 1843.

Margaret MACKEN appears in Townland of Commons of Rouen in Dysert Parish in 1843.

Anyway, if anyone has any information about JANES and MACKEN's I would be eternally grateful! And of course I am happy to share any and all information I have about them living here in the U.S!
