Margaret married Peter Charles McLean of NY in about 1829. They had five known children together:
Charles E. (1831-1897)
Peter Byron (1932-1895)
Washington (1836-bef 1898)
Nathaniel Bruce (1838-1860)
Sarah Amelia (1842-1912) m. John M. Page
She was originally buried in Union Cemetery in Brooklyn. Union Cemetery closed and between 1893-1897 all the bodies were removed and relocated. One section of Cedar Grove was the relocation point, however the records identifying plots have been lost. It is unknown which plot the McLean family occupies.
