Data from the document — Harriet Cooper [verbatim, structured]

• Birth: October 1787 [2 sources]
• Death: 24 Feb 1818 Mendham Morris NJ [2 sources]
• G.192 Find A Grave attests 24 Feb 1820 (stone-tier 3-source corroboration); L.121 tree's 1818 likely incorrect
• Burial: Mendham, Morris County, NJ [1 source = G.192]
• Parents: Samuel Cooper* Sr [[p.472]] × Elizabeth Betsy Brown 1765- [[p.473]]
• Per L.120 Samuel Sr tree, Harriet b. Oct 1787 PREDATES Samuel Sr's 1795 marriage to Elizabeth Brown by 8 years — Harriet was biological daughter of Samuel Sr × 1st (unknown) wife, NOT of Elizabeth Brown
• Marriage: Morris NJ (date not given)
• Spouse: Daniel Losey 1787-1875

• Nehemiah Losey b. ~1807 Mendham Morris NJ d. 1878
• Samuel Mulford Losey b. 14 Sep 1814 Mendham Morris NJ d. 1877
• Baley Ann C. Losey b. 4 Jul 1817 d. 1819 (died age ~2)

Nehemiah Losey 1807 = if Harriet b. Oct 1787, she would have been age 19 at Nehemiah's birth. NOT in G.192 Find A Grave family-members list — = possible that Nehemiah is Daniel Losey's son from a prior marriage OR his birth-year is wrong OR he's a half-sibling.
