The family that Connie O'Mara married into
is definitely the famous von Trapps:
Connie junior knew
the singing family,
her 1st cousins,
and complained that the movie about them was inaccurate.
Etienne Rynne
has Connie O'Mara's wedding invitation and menu 1914,
and "Agathe Trapp"
and her Whitehead relations have signed it.
Apparently
[Anderson, 1998]
mentions "Aunt Connie"
and has a photo of her.
The only question is whether Connie was a governess too,
like Maria.
August Ritter von Trapp,
born "August Trapp",
Bad Homburg,
Germany,
1836
(see here),
Catholic,
Commandant in Austro-Hungarian Navy
(bases on Adriatic),
his exploits at sea earned the family the rank of nobility
and a hereditary title, "Ritter"
means "Sir" or "Knight",
and
"von"
means rank of nobility,
the
English equivalent of their hereditary title is often given as
"Baron",
but the correct equivalent is "Sir August von Trapp,
Baronet",
the "von" did NOT come in with his son Georg's exploits at sea, it was there already,
as shown by
August's gravestone,
which says:
"August Ritter von Trapp",
he died 1884, age 48 yrs,
bur Austrian Naval Cemetery, Pula, Croatia
(then in Austro-Hungarian Empire),
had issue:
Georg Ritter von Trapp,
or "Baron Georg von Trapp",
of the famous singing family,
pron. "Gayorg",
born 1880,
Zadar,
Croatia (then in Austro-Hungarian Empire).
Werner Ritter von Trapp,
or "Baron Werner von Trapp",
born est c.1884,
in
German and Austrian nobility,
all the sons have the title, not just the eldest son,
mar 9th June 1914, Austria
[Etienne Rynne
has invitation, menu, there are arms on it,
which must be those of von Trapp]
to Connie O'Mara [born 8th Sept 1891],
she was supposed to have gone to Vienna,
Austria, as a governess,
married the son of the house,
this is (suspiciously) the same story as that of
Maria,
on the other hand, Connie did marry him,
and what was she doing there if not a governess?,
Werner was killed c.1915 in
WWI,
age est c.31 yrs,
Connie was married, mother and widow all in one year,
had issue:
Connie von Trapp,
Connie junior, Constance,
born c.1915, Muffie de Courcy
met her c.1940, remembered her riding a horse bareback,
lived Bastiengasse 56/3, Vienna 1180, Austria
(see map), Etienne Rynne
met her there 1957,
mar c.1959 (post-1957) to Oskar Hagl [NOT Hegel], no issue,
they lived Bastiengasse 56/3, Vienna,
apparently she was allowed keep the name "von Trapp" after marriage,
since she was the only von Trapp left in Vienna
(after the singing family
had fled to America 1938),
he was an invalid, she had to nurse him,
she visited Ireland 1961,
she died think c.1969, age c.54 yrs.
