I found the obituary of my great grandmother in the Sept 4 1925 edition of the Port Washington News. Here it is verbatim with notes and corrections from me in brackets.
MRS. EMMA B. SMITH PASSES AWAY IN PORT
Mrs. Emma B. Smith, wife of the late Henry T. Smith passed away shortly after 6 o'clock Wednesday evening at the home of her daughter Mary, Mrs. William Pearsall of Litchfield Rd. Mrs. Smith had been ill for some time, having been confined to her bed for the last nine weeks. She was in her 81st year and was born in New York City, the daughter of Peter Moseman [ I can't find a Peter Moseman with a daughter named Emma in 1850 or 1860 census D.S.] in the of Beacon, Westchester County and Mary Smith [ Henry Smith's mother's name was Mary, there may have been some confusion here D.S. ] of Peekskill, N.Y.
Since her husband's death 21 years ago [ an error, it was 23 years prior D.S. ] she has resided with her children in Port Washington. The mother of 13 children, she is survived by 7 sons. George M., Isaac S., Howard, Montrovil, Frank, Wilbur, Thomas; two daughters Eva, Mrs. William Carpenter and Mary, Mrs. William Pearsall; 30 grandchildren and 29 great-grandchildren. Her brother Peter Moseman, of Quincy St. Brooklyn, also survives her. [ I've found this Peter Moseman in the 1900, 1910, 1920, and 1930 censuses ]
On both sides Mrs. Smith comes of famous manufacturing families. On her fathers side were Moseman Bros. harness and leather manufacturers and her brother being Alexander Smith, the well known carpet manufacturer. [ There has to be an error in the relationship here ]
Services will be held at the home of Mrs. Pearsall on Litchfield Road, tomorrow, Saturday, afternoon, at 2 o'clock and interment will be in Nassau Cemetery. The Reverend Hubert C. Jones will officiate. C.E. Remsen is in charge of the funeral arrangements. The deceased was a cousin of Chauncey M. Depew.
