Thank you for taking the time to look up and post this information.
Howard Hudson was apparently into remaking himself to fit any occasion. He married:
11 Oct 1888 in Washington DC
Henry HUDSON Jr. res. Baltimore, MD birthplace New Orleans, LA to: Marie POSTON res. Washington, DC birthplace Virginia by: Samuel W. Haddaway, Minister of the Gospel
14 Jul 1897 in Baltimore, MD
PHILADELPHIA INQUIRER - Married HAINES-FRANCK - On July 14, 1897 at the residence of the bride's parents, Baltimore, MD, by the Rev. J.M. Zimmerman, Minnie L. FRANCK to Howard HAINES of New York.
9 Jul 1899 in Delanco, NJ
Howard HAINES age 42 Boston MA to Mary L. FENTON 29 Bridgeboro, NJ July 9, 1899 Rev. Geo. Whitfield; Witness Jean Russell
By newspaper accounts, he forgot to divorce the first wife before marrying the second and third.
Minnie FRANCK (the second wife and mother of Gwendoline HAINES), died 21 Apr 1899 NJ of Septicemia.
Gwendoline HAINES b. Jun 1898 MD d. 31 Mar 1901 NJ.
Howard and Mary's second child, Gladys HAINES b. 12 Aug 1901 NJ, lived in NJ and was raised by her grandmother Mary Ann BUZBY/FENTON and appears there in the 1910 census.
Howard and Mary, with their son Howard Jr, left NJ in Apr 1902, moved to Ohio and then Detroit and somewhere along the way changed their last name from HAINES back to HUDSON.
At this point, I still have not found any document to confirm the year and place of Howard's birth or if his original name was actually Henry HUDSON.
