According to historical records, four Brahmin families viz. Pakalomaattom, Sankarapuri, Kalli and Kaliyankkal, which were well rooted in the Christian faith, moved from Palayoor to Angamali because of religious persecution. Their exodus was south bound and they settled in Eattumanoor. Our forefathers were members of the Martha Mariam Church, Kuravilangadu (at present a Roman Catholic Church) which was built in AD 337 in Kottayam District. The Elanthoor Thazhayil Family belongs to Kalikavu Kudummam (family) according to historians. The exodus of this family continued when they moved from Kuravilangadu to Nilakkal via Kanjirappally in the beginning of the tenth century AD Among the seven and a half churches (Kodungalloor, Quilon, Chayal or Nilakkal, Niranam, Kokkamangalam, Kottakkavu, Palayoor and Thiruvithamkodu) of the Apostle Thomas, Nilakkal was one which was a commercial centre since the first century A.D. which was situated on the western valley of the Western Ghats of India. Our forefathers left Nilakkal by the end of the thirteenth century and went to Kanjirappally and other places because of the fear of Pariahs of Pandi (Tamilnadu) and wild animals. When they were at Nilakkal they lived on the church complex which was established by St. Thomas and inherited the name of Pallivathukkal which has been used by them in their subsequent itinerary. for example, at present, Roman Catholic families at Kanjirappally are known by this name. This name has been adopted by the families at Kadambanadu, Kuzhikala and Ranni and other places.

A group of our family members moved from Kanjirappally to Kadambanadu (Quilon District) in the beginning of the fourteenth century where they built an ancient church and where a small hill is still known as Nilakkalkkunnu which bears its association with the people who came from Nilakkal. At Kadambanadu, our family name was known as Pallivathukkal. At present there are families at Kadambanadu such as Pallivathukkal, Theruvathu, Thazhayil and Valiaveedu which are the offshoots of the original family tree. Our forefathers were recruited to the local indigenous army led by Kuttanmars (for example the local chieftains) who were experts in Kalaripayattu. Again, the family members received training for local wars or mutinies of the day and under the leadership of Nina and Varkey, they were defeated at a place called Padanilam.

By the fifteenth century, as usual, the exodus of our forefathers continued and reached Thumpamon on the banks of the Achenkoil River where they were instrumental in the construction of a church (a Jacobite Church) with the help of Pakalomattom family. The members of this family are known as Vadakkedathu because they resided at the north side of this new building. The members of our family resided at the south side and were known as by the family 1 name Thekkedathu. Then one group moved to Oomallor where they were known as Tkekkedathu where they constructed a church. The Oomalloor Church was built in the year 1575 and our forefathers had demonstrated a great zeal in the construction of worshipping places. By the end of the second half of the seventeenth century a member of this Tkekkedathu family by the name Koshy moved to Elanthoor (it is "approximately four miles away from Pathanamthitta town of the newly constituted Pathanamthitta District in Kerala State) and settled down at a plot of land called Vallia Thazhayil which is north of the present Pulinthitta Marthoma Church and is also adjacent to the paddy field.
