Early censuses in New York state show him with his family on the 1810 Census in the village of Manlius, Onondaga, New York, and in the 1820 Census, again in Manlius. Manlius is/was a small village about 10 miles southeast of Syracuse. On the 1810 Census, there seem to be 6 children under 15. To date, I have only identified three. Where are those other children? And the ages of the children don't seem to allow for all of them to be the eldest woman's children. Is she his second wife? And who is his wife? See snippet below...
[All are Free White Persons] Manlius NY
Males under 10 : 2
Males 10 thru 15: 1
Males 26 thru 44: 1 [this should be Arnold]
Females under 10: 3
Females 16 thru 25: 1 [this should be mother of children/wife of Arnold]
Total in household : 8
I do wonder about the Females 16 thru 25 - surely it should be in the next column? But I checked the blank form, and it is very clear. The third column past the double lines is for 16 thru 25. Letting her be 25 [maybe turning 26 later that year], that teenaged boy 10 thru 15 could only be hers if she were married at about 14-15 years. Very unusual.
[All are Free White Persons] Manlius NY
Males under 10 : 1
Males 10 thru 15 : 1
Males 16 thru 18 : 1
Males 16 thru 25 : 2 [i.e., 1 male 19-25]
Males 45 and over: 1 [this should be Arnold]
Females under 10 : 1
Females 10 thru 15: 1
Females 26 thru 44: 1 [this should be mother of children/wife of Arnold]
Total in household: 8
Arnold and his wife appear to have had about 7 children, from approximately 1795 to 1816: 4 boys, 3 girls. Of course, at least one of the children on a census might possibly be a neighbour's child, or a relative's child, helping out. No assumptions. The children I have been able to identify are the following:
1) Jacob ORMSBEE [ancestor] b. 21 Jun 1806 Pompey NY, d. 1 Apr 1893 Syracuse NY; m. Sabra TOWERS abt 1824?, 5 children; m. Emily Hurd Dec 1869 Syracuse NY, no children.
2) Stephen Decatur Ormsbee b. 13 Jan 1816 Pompey NY, d. 30 Jul 1893 Syracuse NY; m. Martha Durston abt 1840; 4 children
3) Hannah Ormsbee, b. May 1818 Manlius NY, d. bef 1893 Onondaga Co., NY; m. Henry James Coon abt 1836 in Van Buren Onondaga NY; 5 children.
Clearly, I'm missing possibly 2 males, and 2 females, one of whom [Hannah] would have been only 2 yrs old for the 1820 Census - where was she this census day? Confusing.
In addition, there is a tick mark indicating the Enumerator saw that Arnold was involved in Manufacturing, as were half a dozen other individuals in the same neighbourhood. What could it have been?
Also, I note the residence change for Hannah's birth, b. 1818. [see above]. Either the family moved or, Arnold's wife first deliberately birthed her children in Pompey, then stayed in Manlius for Hannah's birth; between 1816 to 1818 - Manlius lies about 8 miles north of Pompey. This gives me many more questions. Were her parents or at least her mother living in Pompey? Perhaps her mother died between 1816-1818? Did Arnold still have manufacturing concerns in Manlius earlier than 1820, but stayed in Pompey? Note, as a village, Pompey was established in July 1790 by the Land Office Commissioners [New York].
I have been unable to find further details of Arnold and wife. One family tree indicates her name was Hannah/Ann Sherman, but provided no sources. I have found no information of Arnold's wife, including no details of her death date/place. If Arnold died before her, she might well have lived with one of her children - or possibly a sister. But teasing out those bits of information can be quite difficult.
And of course, it could be that I have stumbled on the wrong ORMSBEE in Onondaga county, New York. Although a number of these Ormsbee individuals and their spouses, children, were all buried in the same large plot in Oakwood Cemetery, Syracuse, Onondaga, New York [graves of Graves and Ormsbee]. I do believe I'm correct, but of course, everything could be different!
