When I first searched for David H. McAlpin in the 1870 U.S. Federal Census, I found the following listing for the family in New York (21st District of Ward 21), New York. The official 1870 Federal Census enumeration date was June 1, 1870. However, I like to look at the date that the census taker visited that neighborhood to see how timely the information was. In this case it was July 16, 1870. There is a note to the right of the family that says "In Country, Unknown."

Edwin Augustus McAlpin (1848-1917)
Joseph Rose McAlpin (1853-1888)
George Lodowick McAlpin (1856-1922)
William Willet McAlpin (1858-1925)
Frances Adelaide McAlpin (1860-1937), my great-grandmother
David Hunter McAlpin, Jr. (1862-1934)
(though there may have been a son of the same name who died young)
Charles Williston McAlpin (1865-1942)
John Randolph McAlpin (1870-1893)
The first seven children were listed at the New York address above, but I also found five of them in the census at Hanover Township, Morris County, New Jersey. (Note that this was not the property that he later purchased in Harding Township and named Glen Alpin.) In this case, the date was July 22, 1870. In reviewing the names of the Irish servants in the household, I can see that three (Mary Riley, Rose Riley and Julia Farley) were enumerated twice as well.

Since only five children were listed here, I looked to see if I could find the two oldest, Edwin and Joseph, again in the 1870 Census. I found the oldest son, Edwin (listed as Edward) McAlpin in New York City, in the household with, yes, his father, D.H. McAlpin! (See the image below.) Note the date of this enumeration is December 24, 1870. The source citation provided by Ancestry.com indicates that this is a second enumeration, presumably to count those who were not at home to be counted in the previous July.

Note that D. H. McAlpin's wife was not listed in December. Frances Adelaide (Rose) McAlpin died on November 28, 1870.
In a separate search for Joseph McAlpin (born about 1853), I found him at a boarding school in Connecticut, enumerated on June 7, 1870. The census doesn't indicate the name of the school, but the post office is noted as Ellsworth, which is a section of the Town of Sharon.
