Guecellone IV da Camino

Guecellone IV da Camino (c. 1177–c. 1236), eldest son of Gabriele II, was orphaned at nine and raised under guardians. In 1191 he swore loyalty to Treviso's podesta Ezzelino II da Romano, as the Guelph da Camino and Ghibelline da Romano rivaled over the Marca Trevigiana.

In 1195 the patriarch of Aquileia invested him and his brothers with several castles, and in 1211 they bought further lordships from the bishop of Belluno. Regarded as ancestor of the family's upper branch, he was long believed to have divided the lands with his brother Biaquino in 1233, though modern historians call that division fictitious.
