Frank was the son of Alexander John McClean, who was of Scottish and French-Canadian descent, and of Emma S. Hefter, who was born in Illinois, to German parents. Catherine was the daughter of James Fleming, and was almost certainly of Irish origin.

John’s maternal grandparents were Clemens/Klemens Petronis and Veronica Strelciunas (the daughter of Kasmicrz Strelciunas and Ursula Dalenkiewicz/Dalenikiewicz). Clemens and Veronica were born in Lithuania.

Thought he was Jewish.

Was his mother born in Lithuania or the US?

Isn’t the surname ‘Fleming’ of Belgian heritage? I am just wondering.

andrew October 18, 2014 at 12:09 pm

I would have never thought he is half Lithuanian

Why not?

He’s got the classic curly hair Celtic trait.

Alice November 19, 2014 at 8:22 pm

Nothing to do with being Celtic or not. Celts are a bit of a mystery. There might have been some Celts arrived in the British Isles but like most invaders it is usually the male line. All the British Isles clusters genetically with other Northern European countries like Norway, Holland etc so it is a yet unknown whether the Celtic languages and customs were mainly adopted. You get curly hair in lots of populations but that type of hair is a minority in most countries in Europe.

genetically the british isles are no more norwegian and dutch than they are french and spanish, their genetics vary

Alice November 20, 2014 at 7:22 am

J.J. I’ve had my genetics done and also 3 members of my family and have been looking at the subject for years. Here is a European dna cluster map. All the British Isles clusters with Northern Europe. Every dna study shows this. The Spanish cluster on their own but their closest populations are French and Northern Italian.

Different areas of the British Isles are slightly different with the Irish, Scots and Orcadians together and the southern English a bit closer to Belgians, Northern French etc.

Here’s a few for you to peruse.

This one has a lot of populations including some Middle Eastern. You will have to zoom in to look.

Two great posts. People assign traits to being ‘Celtic’ and ‘Germanic’ when they shouldn’t, strictly speaking they’re linguistic/cultural terms only. The Celts were everywhere from Spain to Germany to Turkey and curly hair like John’s is found in any European country. Like you said all of the British Isles cluster with North Western Europe.

ah i see what you mean now but still england is highly mixed with other european countries while places like norway have only one ethnicity. If you look at a british and a norwegian guy you will notice differences in the stature, nose, eyes and height.

Alice November 29, 2015 at 8:10 pm

@ athelya – England is not highly mixed and Norway is not one ethnicity. All these populations have similar contibutions e.g. Neolithic Farmer, Early European Hunter Gatherer, Steppe ancestry etc. There was a big movement from the Steppes in the Bronze Age which has affected northern Europe more than Southern Europe but most European populations have had contributions from different groups.

Celts now have curly hair?

andrew November 29, 2015 at 12:31 pm

@ follers

to be honest I am not an expert about Lithuanian phenotypes but if they told me this guy was fully Irish I would have believed that. (non Jewish) Lithuanian ancestry is also rare in US.

Alice November 29, 2015 at 8:15 pm

Lithuanian is most likely the biggest contribution to his ancestry. John C Reilly has some similarities to some Irish but there are some differences in his features as well especially the eye area and bridge of his nose.

andrew July 4, 2016 at 4:40 pm

He doesn’t look that different from Colm Meaney and other Irish guys.

justjustin March 17, 2014 at 2:24 pm

John C. Reilly was doing some research last year and discovered that his grandmother on his father’s side, maiden name McLean, was of Scottish heritage.
