By seeing the new gazette in 1949–50 to convert Amboori area into a fully agricultural sector, more families reached here and most of them were Christians. For the new migrants to stay temporarily, a shed has been constructed by Kottakkuzhiyil Joseph Vaidyan and the first Holy Mass was celebrated in this shed by Fr. Adeyadathoos.
