These are tidbits of what I know about the Eskayas. Mariano Sumatra of Loon town went with a priest to Manila (to study perhaps) and surfaced in Mindanao as a pro-Katipunan organizer. He went back to Bohol and settled in Biabas, Guindulman where he started a community that used its own alphabet, signs and languages reportedly to continue his advocacy and evade suspecting authorities. He introduced a communal system of agriculture with him providing the inputs and the farmers giving back to him a portion of their harvest, thus he became a "datahan", someone to whom one makes a "data", or installment payment. While the Eskayas could be considered as a tribe, this may be as far only as their unique social, economic and learning systems. If we consider race, they do not belong to one other than ours. While in Biabas, Anoy frequently visited his hometown and even convinced some of his friends and relatives to join him in Biabas. This may explain why surnames that are common in Loon are carried by some households in Guindulman and in Duero, where another Eskaya community was established. The many Datahans and Sumatras in Bohol are, therefore, blood relatives.
