I have pages from a Mahany family Bible from Homer Michigan. I sent for copies and they turned out not to be my Michgian Mahaneys, but maybe they are yours.
Records the marriage (1840) of David L Mahany (b Northumberland PA 1815) to Sarah A Murray (b Charleton NY 1823) Children all born in Homer MI
Children seem to be Sarah J. (1842), Lydia (1844), William L (1847), Mary E. (1851), Charles H (1854), Ella J. (1857), Bryron S. (1862)
Additonal info regard marriages and deaths.
If this is useful to you, I can send it on.
