Konstantyn Kurcewicz (uncle) Helena Kurcewicz (full name: Helena Kurcewiczówna-Bułyha, later Skrzetuska) is a fictional character appearing in the novel With Fire and Sword by Henryk Sienkiewicz as the main female protagonist.

Helena is a beautiful orphaned princess living with her aunt and cousins in Rozłogi.

Jan Skrzetuski falls in love with her and vies for her hand against the Cossack colonel Bohun to whom she was promised.

The young Cossack fell in love with Helena but she didn't return his feelings.

In 1648, Helena met Polish lieutenant Jan Skrzetuski and they fell in love with each other.

Bohun took the wounded girl to the ravine on the river Dniester in order to hide her.

He put Helena in the Devil's Valley, in the care of his friend - witch Horpyna and left to the war.

After the Siege of Zbarazh and signing the treaty with Cossacks, Helena finally reunited with her beloved Skrzetuski.

In next parts of the Trilogy ("The Deluge" and "Colonel Wolodyjowski") Helena is mentioned sporadically.

Above those eyes dark velvety brows were defined in two delicate arches; her blushing face bloomed like the most beautiful flower, and through her slightly opened lips of raspberry hue were seen teeth like pearls, and from under her hood flowed out rich dark tresses.

[1] While escaping from Bohun's pursuit, she was forced to having her braids cut in order to disguise as a man.
