Sobol got its name from an everflowing spring (ubbog) that had sprouted in the locality . The abundant supply of spring water is the source for domestic consumption and farm irrigation . It seems that the spring was the fountain of life with the elders called it “ Sobol” Later people refer to the whole place as Sobol. This legendary place called Sobol was said to be located between Calupaan and the Ambayaoan River inhabited by settlers from Tagudin , Ilocos  Sur.

            Sobol was originally a sitio of Barrio San Rafael located  just  south of  Calupaan . it is flourishing agricultural and fishing community . Three great  floods had devastated the place that led to the exodus of its inhabitants to higher ground across the southern bank of the Ambayaoan River and to the north of barrio San Roque . The devastating flood in 1935 eroded a big portion of school where almost all the people evacuated . the big flood in 1976 caused by super typhoon “ Didang” made the second wave of evacuation . And finally the 1979 flooding overflowing Ambayaoan River made all the residents to finally decided to transfer totally to the present location of  School .

            Its transfer in 1935 to the proximity of Barrio San Roque had made Sobol a sitio of San Roque . The creation of the PACD in the 60’s which intensified the creation of barangay to foster countryside development led to the creation of Sobol as a separate barangay. This was through the assistance of Atty. Pedrilito Aquino the local COMELEC   chairman at that time and with the initiative of Anastacio Andaya. Barangay Sobol is bounded on the north by the Ambayaoan River on the south by Brgy. San Roque on the east by Brgy. Casaratan; and on the west by Brgy. Legaspi in Tayug . It is about  2½ kilometers away from the town proper.

            Sobol had slowly recovered from its devastating past and it is now rapidly an agricultural community with farming as its primary means of livelihood. Farm products are palay, corn , tobacco , and vegetables like string beans, root crops such as singkamas and tomato fruits. Fishing and livestock raising are the other sources of living.

            The first Teniente del Barrio of Sobol was Severino Trinidad and followed by Billy Villanueva. When Sobol became a Barangay , its first Barangay Captain was Bonifacio Acosta , Sr. followed by Anastacio Andaya and Servillano Villanueva . The present barangay Captain is Ernesto L. Facun , who is serving its second term.

            Brgy. Sobol is a religious community with Roman Catholic as the dominants sect. Followed by the seventh day Adventist and a local sect named Iglesia Watawat ng Lahi . prominent families in the barangay are the Andaya , Layco,Garcia , Castro and Beda?a among others.

            The barangay had gained a lot of important improvements and prominence . Its river banks now are well protected due to the 1995 construction of the three (3) kilometers protection dike along the Ambayaoan River from Sobol up to the town proper. This protection dike served as the road linking the barangay to the Poblacion and replacing the old barangay road constructed through the initiative of the barangay flks in 1983 . Likewise , Brgy. School was the chosen site of the 11^th Diocesian Jamboree for BSP and GSP of Eastern Pangasinan in November 1996.
