Unfortunately, I have spent much time at the archives in person.
The two naturalization/voter's registration cards I have obtained are of Thomas's sons, Michael J. Costello, of West 61st Street, and Patrick H. Costello, of West 100th Street. They each refer to a page that no longer exists.
Patrick H. Costello's Naturalization Card/Voter's Registration Card: Address: 2100 West 100th Street, Ward 1, Precinct J Office # 4645 Volume # 67Page #485 Native of IrelandNaturalized November 1, 1878 In Common Pleas Court, City of Cleveland, Cuyahoga County, Ohio Age when naturalized: 21 years (1878) Age when this card was recorded: 42 years
Cuyahoga County Archives Michael Costello's Naturalization Card/Voter's Registration Card: Address: 3121 West 63rd Street, Ward 2 Precinct G Office # 27374 Volume # 67Page #485 Native of IrelandNaturalized November 1, 1878 In Common Pleas Court, City of Cleveland, Cuyahoga County, Ohio Age when this card was recorded: 42 years Copy of father's papers: name: Thomas Costello 7 January 1918, lived at 5007 Haight, Ward 4, Precinct F
Thomas Cosetllo's naturalization records at the acrchives also mention this "Volume # 67Page #485." However researchers there say it does not exit, and I have looked at volume 67 on microfilm, and THAT only goes up to 200 pages. The researchers at the archives say that it might just mean that Patrick, Michael and Thomas stood in a room with several other people listed on that page 485.
How about church records? The church at which Mary's services were held and presumably, at which she was a member, was: St Ignatius of Antioch Church 10205 Lorain Avenue Cleveland, OH44111 Tel: 216-251-0300
That I have also pursued, but it has been hard for me to meet with that church's officials on a good time to look at their records. The church's records may be the best source for Mary's burial, however, as Holy Cross Cemetery, which oversees the Catholic cemetery in Olmsted Falls, does not have the location of Mary's burial.
