It's always confusing when written down, which is why the good Royal books have family trees, where all the relationships become clear and suddenly make sense.
Prince William of Denmark, who became King of Greece as George I, had 8 children by his wife Grand Duchess Olga of Russia.
Two of their sons were Prince Constantine and Prince Andrew.
became King, and had six children by his wife Princess Sophie of Prussia (who was Kaiser Wilhelm's sister). The three sons all became Kings of Greece: George II, Alexander, and Paul.
King Paul had three children by his wife Princess Frederika of Hanover (the sister of Prince Ernst August's father) including Queen Sophia of Spain, and King Constantine
married Princess Alice of Battenberg, and had four daughters and one son, the present Prince Philip
, Duke of Edinburgh.
The daughters (ie Prince Philip's sisters) are quite interesting:
married the Prince of Hohenlohe-Langenburg;
married the Margrave of Baden;
married the Grand Duke of Hesse and by Rhine and was killed along with her husband, two young sons and mother-in-law in a tragic air crash in Belgium in 1937;
married Prince Christoph of Hesse, who was killed in action in WWII, and married secondly Prince Georg Wilhelm of Hanover (still alive today) who is the brother of Queen Frederika and uncle of Prince Ernst August (Caroline of Monaco's husband).
On the Hanover
connection: Kaiser Wilhelm had one daughter, Princess Viktoria-Luise. She married Prince Ernst August (III), Duke of Brunswick-Luneburg, Prince of Hanover, and was the mother of Ernst August (IV), Georg Wilhem and Frederika.
Another brother of Constantine and Andrew, Prince Nicholas, married Grand Duchess Helen of Russia; one of their daughters, Princess Marina, married the Duke of Kent, father of the current Duke of Kent
I hope this makes things easier to understand; it can get quite complicated!
