The 1905 New York State census helped me locate the family of Moses and Mathilde Rothschild’s second-born son Rudolph; he was living with his wife Rebecca and their two children in New York City and working as a salesman. It looks like he was a “hail” salesman, but given how badly the enumerator spelled their names, I assume Rudolph was not selling frozen precipitation.

But what about Rudolph’s mother and siblings? What does the New York State census show for them in 1905? His mother Mathilde and the three youngest children—Theresa (26), Gertrude (24), and Aaron (22)—were living together in New York City, and Gertrude was working as a stenographer and Aaron as a bookkeeper. Theresa and her mother listed their occupations as housework.

Samuel Rothschild and his wife Sallie also were living in New York City in 1905, and Samuel was working as a “superintendent,” specifics not given.¹ His brother Albert was working as a traveling salesman and living in the Bronx with his wife Rose and daughters Rachael (or Rae, age 9) and Josephine,² who was born on November 19, 1902.³

By 1910, there had been quite a few changes, including marriages, babies, and many relocations from Manhattan to the Bronx. Mathilde had moved from Manhattan to the Bronx and was living only with Aaron, her youngest child. Aaron was working as a traveling salesman in the trimmings business.⁴

Moses and Mathilde’s two daughters married between the 1905 NYS census and the 1910 US census. Theresa married Max Alexander on June 15, 1905, not long after that NYS census was enumerated.⁵ Max was born in New York on September 18, 1874, to Henry Alexander and Fannie Meyer.⁶ Theresa and Max had their first child on May 13, 1906, a daughter Frances.⁷ In 1910, Theresa, Max, and Frances were living in the Bronx, and Max had his own real estate office.⁸

Theresa’s sister Gertrude married Charles Lancelotti on November 27, 1907, in New York City. Charles was born in Italy on October 1, 1882, to Raphael Lancelotti  and Maria De Rosa.⁹ He had immigrated with his parents to the US as a young child. In 1900 he had been living with his parents and siblings in New York, working as a carpenter. In 1905, he was working as a bookkeeper. Gertrude and Charles’ first child, Milton, was born on November 23, 1908, in New York, and in 1910, they were all living in the Bronx, and Charles was working as an artist for an engraving company.¹⁰

Meanwhile, the three older sons of Moses and Mathilde Rothschild were also all living in the Bronx in 1910. Samuel and his wife and son were living in the Bronx and Samuel was a superintendent of a comb factory.¹¹ Rudolph and his family were also in the Bronx, and Rudolph continued to work as a traveling salesman.¹²

And Albert and his family also were in the Bronx, and Albert was working as a traveling furniture salesman. Albert’s family, however, had expanded since the 1905 NYS census. He and his wife Rose now had two more daughters: Theresa, born January 5, 1906,¹² and Lillian, born December 9, 1909.¹³ Since Rose reported on the 1910 census that she had had six children of whom only four were living, I assume that there may have been another child who died before 1910 in addition to their son Milton, but I cannot find a birth or death record for that child.

Thus, in 1910 Moses Rothschild’s widow Mathilde and their six children and nine grandchildren were all living in the Bronx. Here’s a map showing where they were located as of that date.

But the next decade saw many changes, including departures from the Bronx.
