The 1900 Census of Jersey City has the family living at an apartment building located at 265 Baldwin Avenue. Thomas P. Olwell is listed as the head of the family age 34 years and having been born June 1865. It also lists him as a native of Ireland, having been in the U.S. for 10 years, arriving in 1890. His occupation is listed as a grocery clerk , currently employed. His both parents were from Ireland. Alice was listed as his wife, born September 1870 - age 29. It also lists both her parents as being born in Ireland. The next question box is of great interest to us. It asks how many years married and the first number written in was 12 but it was changed to 4. So assuming this is correct, she was married to Thomas Olwell for 4 years and married William Barnes 12 years prior - 1888. This would seem possible as Alice and William Barnes’ first child was born 1889. Lillian is listed next as a daughter born May 1897. Next listed were Marion Barnes and Adele Barnes, listed as step-daughters. They were both listed as students. The birth locations of all children, even three year old Lillian was New York. Alice was pregnant at the time of this census, giving birth to Anna Kathlyn in September, so this census was taken before this as she is not listed.

On July 12, 1916, Thomas P. Olwell died. His address at that time was 439 E. 142 Street. So the family, at moved from Jersey City to the Bronx sometime between June of 1900 and his date of death. At the time of her marriage (1914) , Marion Barnes was living at 1138 Bryant Avenue.
