General Notes

Source:  A Mary Gray keeps appearing in the Macosquin Presbyterian Church Communicants Roll Book from circa 1874 onwards and she also witnesses James Gray's wedding in 1888.  She must be another sibling of James, William, Robert, Samuel, Margaret, Margaret and Hester.  International Genealogical Index gives her middle name as Jane.

There is some evidence to suggest that this lady immigrated to the United States and is living with her aunt, Eliza Burk nee Gray (except that the ages are wildly out - 22/17 compared to 30 - but then American census data is frequently inaccurate):

1900 Census: Manhattan, ED 153, 220 W. 16th St. (tenement) Mary J. Gray, seamstress: age 22/17, b June 1882, Ireland, emig in 1895 five years in US, living with William Gray, age  44 and Elizabeth Burk, aunt, age 70 wd. (NB - no Mary Gray found at EIR arriving between 1890 and 1900 aged circa 13 years old.)

1910 Census: NY, Manhattan, ED 829,Ward 16 (Apr 29)
141 W. 15th ST, Mary J. Gray Lodger W, age 29, Ire Ire Ire emig in 1900/designer. wallpaper factory??????? did she marry?

1920 Census: NY, Manhattan Ed 1388 (taken Jan 6, 1920) 2280 Third Ave, nr E. 12th St. Mary J. Gray, head, age 38(b 1882), single, emig 1905 , Ire, Ire, Ire, private housework??????????

I also checked 1878, 1882 and 1883 for Irish civil birth record of Mary J. Gray and found none at Derry FHL but that doesn't mean much.

Most telling of all perhaps, Mary Gray, sister of my James Gray disappears from Macosquin Presbyterian church Communicants Roll Book after he last attendance in May 1895, while her family continued attending and that is the year Mary Jane Gray says she immigrated to the United States!
