A line in a New York Herald Brooklyn real-estate transactions column, June 3, 1921, page 18, reports a documented sale of 241a Windsor Place by the Trump Realty Company Inc on behalf of the estate of Mrs Annie Kalkhof, to a buyer named James MacAlpine. The property is described as a two-story house, 17 feet wide. The Brooklyn brokers of record were Harry Lewis (for the buyer) and James Eden (acting for the seller).
Harry Lewis sold for James Eden [to] James MacAlpine the two- story house 241a Windsor Place, 17x[100], [from] the Trump Realty Company Inc Old Brooklyn for the estate [of] Mrs Annie Kalkhof.

The Trump Realty Company Inc was the Brooklyn real-estate business founded by Friedrich Trump— Donald Trump's grandfather. Friedrich emigrated from the Kingdom of Bavaria to New York in 1885, made money in the Klondike Gold Rush hospitality trade in the late 1890s, returned to Queens, and by 1908 had set up a Brooklyn real-estate business. He died of the Spanish flu in May 1918. After his death his widow Elizabeth Christ Trumptook over the operation and, with the family attorney's help, ran the business under the Trump Realty name until her son Fred Trump (then a teenager) finished his training and took on the principal role. By the time of this June 1921 transaction, Elizabeth Trump and Fred Trump together were the operational principals.
The phrasing “Trump Realty Company Inc Old Brooklyn” in the Herald's text suggests the listing was being managed from the Trump office in the older central-Brooklyn area (as opposed to outer Queens, where the family lived).
The property was at 241a Windsor Place. The “a” suffix indicates a sub-divided lot or an additional building behind a main house — common Brooklyn practice for rear-yard cottages on narrow row-house lots. The house was two stories, 17 feet wide on the Windsor Place frontage. (For comparison, the 1900 Riegel deed property a few blocks south on Greenwood Avenue was 23 feet wide.)
The sale was from the estate of Mrs Annie Kalkhof — so Mrs Kalkhof had died, and the executors of her estate were liquidating her real-estate holdings. The buyer was James MacAlpine. The selling broker was James Eden; the buyer's broker was Harry Lewis. The Trump Realty Company was the manager handling the listing.
The 241a Trump sale was not the only Harry Lewis transaction on Windsor Place's west side in 1921. The same Herald real-estate column, in its April 23 1921 issue (page 18), reports:
Harry Lewis sold for Edward McCoy the two-story dwelling 17x100 [at] 247a Windsor Place [to] Ellen Henry. Charles Partridge leased the corner store [at] Atlantic Avenue. Frank Seave sold the three-family house [on] Bay Ridge Avenue for George Heuser. William Harmon Inc sold lots and plots [in] their South Waverly tract...
— New York Herald, April 23, 1921, page 18 (loc.gov).
Six weeks before the Trump-managed 241a sale, the same Brooklyn broker Harry Lewis closed an identically-structured deal on 247a Windsor Place: same west-side back-yard subdivision (“a” suffix), same 17-foot frontage, same 17'-by-100' lot, same 2-story house. Different principals: Edward McCoy as the seller (not an estate-of) and Ellen Henry as the buyer. So in the spring of 1921 there was an active Harry Lewis pipeline of west-side Windsor Place back-yard sub-divisions changing hands — at least 247a (April) and 241a (June, the Trump-managed one).
By July 1922 the 247a property has a different occupant: a Mrs William Delaney, who hosted a miscellaneous shower at her home at 247a Windsor Place for her daughter, Miss Loretta Maud Delaney, per the NY Herald July 30 1922 page 37 society column. So in the year between the April 1921 Lewis sale and the July 1922 society column, Ellen Henry either resold to Mrs Delaney or rented to her. The Delaney family — Mrs William Delaney + daughter Loretta Maud — joins our documented Windsor Place residents.
The 1906 Sanborn fire-insurance map (see the Sanborn finding) covered Windsor Place addresses 1-253; address 241 is in our inventory. The 241a sub-lot may have been added after 1906. Our 1906 Sanborn data for 241 Windsor Place shows it on the west (odd-numbered) side, frame construction, 2 stories — matching the 2-story description in the Herald.
The selling price is not recorded in the Herald snippet (the real-estate column ran abbreviated transactions; prices typically appeared in NYC ACRIS conveyance records, not the newspaper). The name “Annie Kalkhof” is uncommon enough that a follow-up search of Brooklyn deed records for 241 Windsor Place conveyances 1900-1921 should locate her — and identify when she (or her family) acquired the property.
