The island of Gotland off the east coast of Sweden has a couple smaller islands on the western side, one of which is Stora Karlsö. The Stora Förvar cave is on that small western island. The Stora Förvar 11 sample was obtained in 1887.
The age is 5550-5300 BC and the context of the culture is Late Mesolithic.
When originally published, no definitive Y-DNA haplogroup was given. Stora Förvar 11 was noted as positive for a CT, which is ancestral to F and then I. I believe that this sample deserves more attention in our community because while the Y-DNA haplogroup was not published in a paper, hobbyists like us have determined a very significant fact:
Stora Förvar 11 was I1
This was determined by Genetiker but also corroborated by reputable posters on another forum. I took the data and confirmed it independently. Stora Förvar 11 definitely has I1 SNP calls. He is positive for:

This is very significant due to the lack of ancient I1 samples. Previously I had only read of BAB5 from the LBK culture in Hungary. What's even more interesting is that this sample is estimated to be contemporary to BAB5
So we have the earliest I1 confirmed at the same time from Hungary to Gotland (Sweden). That is a rather large spread. Was there a lot of I1 in this area or were these outliers?
The autosomal data is equally exciting. http://linearpopulationmodel.blogspot.com/2015/04/eurogenes-admixture-results-for-motala.html
Stora Förvar 11 is 72% Euro HG, 8% EEF, 17% N. Caucus while BAB5 is 90% EEF and about 10% Euro HG. The above link shows a comparison with the Motala hunter/gatherers who were I2a1 and pure Euro HG. So we not only have a large geographical spread of ancient contemporary I1 but also a large autosomal gap, even though both samples do contain EEF components. In fact, all I1 samples that I've seen contain an EEF component, while we have many I2 samples with zero EEF. For both SF11 and BAB5, the small 8-10% component indicates either an older mixture of the EEF and Euro HG population or a direct mixing 4-6 generations back.
The mtDNA were U5a1 for SF11 and H for BAB5.
Does the 17% N. Caucus also raise eyebrows? I thought that component didn't enter Europe until IE expansion, but I don't know enough to make this determination (thus this thread).
I'm going to include this along with additional info sometime in the I1 section in the future. I put this in neolithic instead of paleolithic and mesolithic because it's just before the farming spread to the area and the sample contained a portion of EEF DNA.
