Previous lords namely Ambazhathunkal Karthas were removed from their posts and a large portion of the land then came under the tenancy of the Kolathettu family who had migrated to Kooroppada from Kolathunadu in Malabar.
The area including Mathrumala was inhabited by farm laborers of the Paraya community who worked in the land owned by the Kolathettu family.
These farm labourers had their Kuladevata (deity), called Saptamathrukkal, installed on hilltop and regular offerings were made.
In the early 1950s, Mathrumala was inherited by the progeny of Kolathettu family namely Chempakasseril Thankamma, Tharavattathil Pappiyamma, Champakara Savithriyamma and Asariparambil Gopala Pillai.
In 1967, Mulanthanathu G. Raman Nair and his sisters who inherited the property filed a case in Kottayam Munsiff Court.
