I've gathered several pieces of information since I posted my original query in 1998. I have William Marriott's obituary, his will and a copy of his marriage record (the latter thanks to a Lawrence cousin, Betty Walling). These items are posted below. I am most interested in exchanging information with any descendants of his brother Alexander Marriott's children, Harriet, Alexander, George and William Thomas Marriott. I would also like to find out who the Edwin and Carolyn Seawill are (see his will, below, Item 14).

The Death Record
William T. Marriott
One of the pioneer residents of this city and a man who has been closely identified with its growth and progress, died at his residence, on Ninth street near Ninth avenue, at 7 oÂ’clock this morning aged 67 years, 8 months, and 2 days. Death was caused by a complication of diseases resulting from diabetes. His death was sudden but not unexpected, as he was confined to his bed for 2 days past.
Deceased was born in Royston, Cambridgeshire, Eng., October 13, 1825. He married Miss Harriet Lawrence in 1846, while yet in England. There were no children to the union and his wife died September 11, 1884. His only living relatives are a nephew, R. Parsons, of this city, a sister-in-law, Miss Flora Webb, who has been his housekeeper since his wifeÂ’s death, and a brother named Alexander, residing in Cambridge, England.
Mr. Marriott came to America in 1851, landing at Philadelphia where he worked as a painter. Later he became foreman of painters for the P.R.R. While acting in this capacity he put the first paint on the original Susquehanna bridge and painted every division of the P.R.R. from Altoona to Harrisburg. In 1853 he tried braking for a short time, his run being between Harrisburg and Intersection. While thus employed he put the first bell cord on a passenger train, using a clothesline and snap hooks, under the direction of General Rumford, of Harrisburg. In 1854 he went west, but not liking the country, returned to Altoona and purchased a small property on fourteenth avenue from Clement Jaggard and made it his residence. He became an employe of the P.R.R. and remained such for more than sixteen years following.
Anticipating the future growth of the city, Mr. Marriott took advantage of the real estate boom and has owned some of the most valuable property in the city. Among these were three lots of ground on Thirteenth avenue and Twelfth street, which he purchased in 1855 and which are now in possession of D. K. Ramey. In 1856 he bought what is now known as the Marriott corner, on Ninth avenue and Ninth street, and made it his residence until 1864. The handsome residence at that place in which he died was erected by him about four years ago. In 1874 he purchased the old market house property, on Eleventh avenue and Eleventh street, and retained possession of it until 1888, when he sold it to W. W. Rouss, who transformed it into the present Eleventh Avenue opera house. He also owned at various times the corner now occupied by the Central hotel, the Streit corner, on Tenth avenue adjoining it, the corner opposite the Marriott House and many others whose value is at present in the hundreds of thousands.
Mr. Marriott was well known among the older portion of our citizens, being made especially prominent by his connection, as proprietor and manager, with the old opera house, which relation he sustained for over thirteen years. He is in every sense a self-made man, his father and mother having died when he was but a youth. His accumulations were not the result of chance but of hard work and shrewd business methods. Though a member of no special religious denomination, he was looked upon as an honest, moral man, and enjoyed the respect and esteem of those who knew him.
The funeral services will take place at 2 oÂ’clock on Saturday afternoon, Rev. Allen Sheldon Woodle officiating. Interment in Fairview cemetery.
