Thomas Brown and Ann Ballantine.

Hi,  I am searching for a possible marriage between Thomas Brown and Ann Ballantine some time during the late 1850s or early 1860s.   They migrated to England during the early 1860s and settled in Manchester, Lancashire.   I have all the information about them and all of their descendants after they arrived in England. And would be delighted to share it.  I wouldn't know anything of their religious beliefs in Ireland, but, they followed the R.C. faith after they settled in England.  Any help whatsoever would be gratefully received.     Thanks.        Don Brown.
