Child, fantasy book with a boy, a family curse(tronado) (strongwood family or similar), hidden keys and green eyed seagulls.

[SOLVED; Wind Tamer; cap: @finnssmile] A book i read when i was a kid: There is this boy, he lives in a small made up city , i believe in a mountain top or similar, his family is cursed by a tornado which hits them every X years (9 i guess) The story of the book is basically the boy trying to find this "keys" his father (a banker) hid from him (in his house, above door marks and such) related to his family curse to 'uncurse' them. I read this book when i was really young so some parts might be similar to what i said, but two parts that maked me where this ones:

Once he was telling about his family history, his grand grand parent or such was travelling down a road and met an old men, the grand parent was arrogant and the old man, who was a mage set a curse on them, part of the effects of the curse is that his surname, once strongwood/strongman, was corrupted by time to mean strongweed/stringwood/etc or something similar to the first name.

The second part i remember is that there were a lot of seaguls in this book, and they were quite important, once in the book the kid was looking up to the sky and saw a weird cloud, that was in actually a lot of seagulls with green eyes.

Once i literally threw some part of this on google and it showed me the book, but i cannot find it anymore. Super sad.
