Alexandrina and Grigore had three sons, all of them born between 1900 and 1905, before both parents resumed their public careers.
In 1910, Alexandrina joined a Romanian Orthodox philanthropic society, the National Orthodox Society of Romanian Women (Societatea Ortodoxă Națională a Femeilor Române, SONFR).
While she is most often credited as a founding member, the Society might have existed under a different name as early as 1893, with Ecaterina Cantacuzino, Gheorghe's wife, as its President.

The central core of SONFR was a group of high-society ladies, including Alexandrina Cantacuzino and, among others, Zoe Râmniceanu, Elena Odobescu, Anastasia Filipescu, Maria Glagoveanu, Sultana Miclescu and Zetta Manu.
As indicated by the name, SONFR was situated on the conservative right of Romanian feminism, where it "reinforced women's traditional roles as mothers and wives", being entirely apolitical.
However, the Society was soon involved in a number of adjacent projects, such as disseminating propaganda among the Romanians of Transylvania, Bukovina, and other parts of Austria-Hungary, and circulating letters of protest against Magyarization.

Although SONFR was sponsored by "the Nawab" and other mainline Conservatives, such ideological positions resonated with the National Liberal program of Spiru Haret, the Education Minister, who offered his full support.
With such sources of revenue, supplemented by bank loans and private donations, SONFR established two girls' schools, 17 kindergartens (the first of which was in Dorobanți), and 22 public libraries.
Some of its funds went directly into purchasing land for Romanian peasant communities in Transylvania and elsewhere, with schools being built as far afield as Chernowitz, Geaca, and Markovac.

SONFR's more formal mission was to combat "foreign religious propaganda" and "the foreign educational establishments", which it described as sources of corruption for young Romanian women.
According to historian Alin Ciupală, these goals should be seen as reflecting the "borderline intolerant" position of Romanian Orthodoxy, but not particularly conclusive at that: "We believe that SONFR's would-be alliance with the Church determined the adoption by the Ladies' Society leadership of ideas circulated by some Orthodox hierarchs, especially those concerning Catholicism, but mostly with a tactical goal in mind. [...]
Moreover, one might mention here the organizers' intent to make use, as it did, of the Church-controlled, nation-wide, infrastructure: the priests as instruments for propaganda and the influence, not just moral, of the leading Orthodox hierarchs."

SONFR members included liberal suffragettes, such as Calypso Botez; Cantacuzino herself was less clearly affiliated with this current, although she did describe herself a "feminist".
As noted by gender historian Roxana Cheșchebec, Cantacuzino was primarily an elitist, who believed in fulfilling a "historic mission of the upper classes", focusing on assisting "the socially disadvantaged as a way of serving the country and the nation."
The same is noted by Pruteanu, who also records her claim that Romanian nobility lived "outside the murderous luxury that surrounds us."
Pruteanu believes that Cantacuzino was "confused", with "a fractured identity", forever oscillating between "conformism and rebellion."

Meanwhile, in 1913, Grigore was appointed Mayor of Bucharest in the wake of the "Tramcar Affair", which had besmirched the opposition National Liberal Party.
According to contemporary sources, he owed his appointment exclusively to "the Nawab", who was at the time performing his last official function, that of Senate President.
The immensely large Cantacuzino estate was split between the two sons, both of whom used the Zamora Castle of Bușteni.
It was to serve as a frequent retreat for the Romanian royal family.
In 1915, Alexandrina also inherited the properties of her adoptive father, including Ciocănești.
