My reference on 508th PIR indicates that 1Lt. Jatros was Company Commander of F Company--you are correct--2nd Battalion.
Notation indicates he died at or near Wylerbaan.Initially he was buried at Molenhoek in B-4-79, and later interred at Margraten F-4-24.
When you look at the photo of the cemetery that accompanies his citation at the ABMC name search site, Section F is unfortunately to the left of the grass boulevard and thus out of frame.However, If you go to the main ABMC page and click on "Cemeteries" then go to the Netherlands page, you can download the booklet about the cemetery on Adobe.Check the black and white aerial view.Starting at the "square" memorial bell tower,the first section is plot B and Plot F is the second group of graves down the main grass boulevard on the right.The rows in each plot start numbering closest to the bell tower, so Row 4 would be the fourth row in from the lane between Plot B and Plot F.Further down the booklet at about page 15 is a photo titled "Graves and Tower Area"This is taken just behind Plot A and the three rows on the left of the photo are rows 1,2, and 3 of Plot E.If you follow this line of headstones to the left you will see where Plot E/F divide and get an idea of exactly where his marker is relative to the Tower.
Margraten is a beautiful facility.I was there 4 days after 9/11 and there were hundreds of flower bouquets in front of the tower that were left by the Dutch expressing their thanks for the services and sacrifices of the American GIs buried there, and their solidarity with the USA in regard to the events of 9/11.It was incredible.
