Yes , it's true. In this resumen from Wiki, there are E-M81 too in France, but in very localized areas, mainly Paris, a city that has hosted emigration for centuries. In rest of Europe is rare, being more habitual E-M78.
In Europe, E-M81 is found everywhere but mostly in the
Iberian Peninsula, where unlike in the rest of Europe
[Note 6] it is more common than E-M78, with an average frequency of 4-5.6%. Its frequencies are higher in the western half of the peninsula with frequencies reaching 8% in
Extremadura and South Portugal, 9% in
Galicia, 10% in Western
Andalusia and Northwest
Castile and 9% to 17% in
Cantabria.
[18][29][30][31][32] The highest frequencies of this clade found so far in Europe were observed in the
Pasiegos from
Cantabria, ranging from 18% (8/45)
[32] to 41% (23/56).
[2] An average frequency of 8.28% (54/652) has also been reported in the Spanish
Canary Islands with frequencies over 10% in the three largest islands of
Tenerife (10.68%),
Gran Canaria (11.54%) and
Fuerteventura (13.33%).
[33]
E-M81 is also found in
France,
[2] 2.70 % (15/555) overall with frequencies surpassing 5% in
Auvergne (5/89) and
Île-de-France (5/91),
[34][35] in
Sicily (approximately 2% overall, but up to 7% in
Piazza Armerina),
[36] and in slightly lower frequencies in continental
Italy (especially near
Lucera)
[31] possibly due to ancient migrations during the
Islamic,
Roman, and
Carthaginian empires.
As a result of its old world distribution, this sub-clade is found throughout
Latin America, for example 6.1% in
Cuba,
[37] 5.4% in
Brazil (Rio de Janeiro),
[Note 7] and among
Hispanic men from
California and
Hawaii 2.4%.
[38]
In smaller numbers, E-M81 men can be found in areas in contact with the Maghreb, both around the Sahara, in places like
Sudan, and around the Mediterranean in places like
Lebanon,
Turkey, and amongst
Sephardic Jews.
Porcentages naturally vary from one study to another, and the smaller the sample is more variation will be.
But two facts are proved: the origin of the E-M81 is Berber and Spain and Portugal are the countries of Europe where E-M81 is the most common. It could not be otherwise, since both countries have been closely connected with North Africa.
