Philly Death record

Her death notice gives her age as 81 in 1905 = 1824 and the 1900 census gives her DoB as May 1825.  However, she gives her age as 26 in her 1844 Immigration Record = 1818.  She has a son, Robert, aged 6 (= 1838 DoB) and a daughter aged 4 with her, so I suspect the age of the son is correct as why lie about the age of a 6 year old.  That makes her 20 when he was born.  If she was born in 1824 or 1825, she would only have been 13 or 14 when Robert was born.

BB, using death notice in the Philly Enquirer: She died Sept 25,1905, aged 81 and was buried Sept 28 in Mt. Moriah Cemetery in Philly.

One census says born in Ire and ones say PA

Died the day after her brother of Catonic Fever which, since he died of cholera, is also probably cholera.

BB: Sarah Jane McAllister died Oct 24 1890

BB: The following were baptisms for the children of Charles and Sarah Gray in 1st Reformed Presbyterian Church in Philadelphia:
1.  Joseph C Gray  bap May 5 1845
2. Sarah Jane Gray bap May 5 1845
3. Charles Gray bap June 6 1847
4. Hannah Gray bap June 2d 1849 (probably Susannah on the tree)
5. Mary Jane Gray bap June 2d 1849
6. Mary Ann Gray bap July 4 1852 (b. Jan 10 1852)
7. Matilda Gray  bap July 4 1852 - no parents given
8. Emily Gray bap Nov 2 1856
9. Margaret Gray bap Apr 6 1861 (b Aug? 7 1860)
I also have found 2 stillborn deaths which may belong to this couple in 1840 and Dec 1845.  The Dec 1845 record only states the father as Chas Gray.  Sarah Gray states in the 1900 Census that she had 10 children and 5 were then living.  There was also an Isabella Gray bap Jan 2 1842 in this church who may be the first child of this couple.  I don't have her above.
The interesting note here is that Joseph's middle name starts with a C which leads me to believe Sarah may have been a Crowe or a Creelman.  Since she is attending the same church as Nancy Creelman Brewster she may be her older sister.  However, the Crowes also belong to this Church.
Some of these children do not have parents recorded and at a later date someone has gone through and added a few parents and corrected some spelling of names!  This was the only Gray family with recorded baptisms at this date.  There is an earlier Gray family having children baptized in the 1820s which may prove helpful later.
