I'm looking for any help on information on my gx3 grandmother, Mary McKeon or McKeogh/Keough. (the pastor spelled her name different ways on various records)

She was born February 1846 according to her death record, daughter of Peter McKeough/Keon and Mary O'Brien.

She emigrated to Glen Cove, NY in 1860 and married James Kenary/Kinneary.

I'd appreciate any help. Thanks.
