Here is a picture showing him at the occasion of Steinitz' visit at the New Orleans Chess, Checkers and Whist Club: http://commons.wikimedia.org/wiki/F....

On C A Seguin 's page there are some serious doubts that C.A. Seguin was the one who played Morphy in a blindfold simul in 1858 in Paris. I wonder if that French player is the one who played this one in New Orleans: Steinitz vs C A Seguin, 1883. Maybe this was played by J.D. instead.

<SEGUIN-On Tuesday, Nov. 28, 1916, at 3 o'clock p.m., in Brooklyn, N. Y., JAMES DE BENNEVILLE SEGUIN, aged 63 years, a native of New Orleans. Interment in Brooklyn, Friday morning. <New Orleans Times-Picayune, 1916.11.29, p2>>

<John [sic] D. Sedgwyn 57 [sic] years old, of 387 Clinton street, for eleven years a proofreader with The Eagle, and for several years a chess expert for Southern newspapers, died yesterday afternoon at his home, after a lingering illness. Mr. Sedgwyn was born in New Orleans, La., son of Dr. James T. Sedgwyn, a prominent physician of that city. He came to Brooklyn about twenty years ago and had lived here ever since. He is survived by his widow, Laura T. Sedgwyn. The funeral services will be held Friday morning, with a requiem mass in St. Stephen's R. C. Church. Hicks and Summit streets, interment following in Holy Cross Cemetery. <Brooklyn Daily Eagle, 1916.11.29, p3>>

<A requiem mass was celebrated in St. Stephen's R. C. Church to-day for John [sic] D. Sedgwyn, 57 [sic], who died Tuesday at his home, 387 Cliton [sic] street. Interment followed in Holy Cross Cemetery. Mr. Sedgwyn was for eleven years a proofreader on the Brooklyn aDily [sic] Eagle and for sometime a chess expert for Southern newspapers. He was born in New Orleans, the son of Dr. James T. [sic] Sedgwyn, a prominent physician of that city, and came to Brooklyn about 20 years ago. <Brooklyn Times Union, 1916.12.01, p8>>

The family history goes something like this:
André Séguin (grandfather, shipyard builder in New Orleans)

Dr. James F. Séguin (father, b. 1815.11.23 Philadelphia; d. 1890.12.20 New Orleans, obit: Times-Democrat, 1890.12.22, p3)

Four sons all survived the death of James F. (of which two were chess players):

James D. Séguin (b. 1853.09.11 New Orleans; d. 1916.11.28 Brooklyn)

André William Séguin (brother, b. 1866.02.24 New Orleans, d. 1932.07.13)

I have yet to confirm the identity of the other two brothers...

Now James D. Séguin married Laura Templeton Harvey (b. 1854.06.10, d. 1940.07.27) and had two children:

Louise Maria Séguin (b. 1878.06.21 New Orleans, d. 1944.10.08 New Orleans)

James D. Séguin Jr (b. 1879.06.21 New Orleans, d. 1940.07.22 five days before his mother)

Both Louise and James Jr played chess and Louise even helped with the Times-Democrat column according to the ACB: https://books.google.com/books?id=l...

<<thomastonk:> According to Gaige's "Chess Personalia", James DeBenneville Séguin died on November 11, 1916.>

Then I found the following advertisement in the New Orleans Times-Democrat, 1901.06.16, Part II, page 13: "Auction Sales by Fitzpatrick & Brennan. Contents of Residence of J. D. Seguin, Esq., on account of relinquishing housekeeping, at auction, Monday, June 17, at 11 a.m. at 1322 Peters Avenue, corner of Prytania street." The advertisement goes on to list things from his library, antiques, and modern items that will be up for auction. It also mentions "the right to occupy 1322 Peters avenue from June 25 to Oct. 1, 1901, which will be sold at 11 o'clock sharp."

Now there is a legal case involving James D. Séguin and what seems to be fiduciary malpractice. This case appears to have started in a lower court in 1900 and ran until Jan 21, 1907 (where the Louisiana Supreme Court ruled Séguin was absolved of the responsibility). Perhaps this case had impacted Séguin's ability to earn an income as an attorney in 1900, and ruined him financially, resulting in the loss of his home and possessions?

In 1907 a "John D. Sedgwyn" turns up in Brooklyn newspapers. Specifically at a June wedding held at Holy Cross (the same church that held John D. Sedgwyn's funeral in 1916) and mentioned in the Brooklyn Daily Eagle, 1907.06.23, Section 5, page 5.
