In this paper, we study to find out the major causes that are hindering/affecting the happiness in family using Combined Disjoint Block Fuzzy Cognitive Maps (CDBFCM). We find that happiness is strongly correlated with perceived good health. This method is introduced by W.B. Vasantha Kandasamy, is analyzed in this paper. The Combined Disjoint Block FCM is defined in this method becomes effective when the number of concepts can be grouped and are in large numbers. This paper has five sections. First section gives the information about development of Fuzzy Cognitive Maps and happiness in the family life. Second Section gives basic notations and definitions of Fuzzy Cognitive maps and Combined Disjoint Block Fuzzy Cognitive Maps. In Section three, we explain method of determining the hidden pattern. In the fourth section, we give the concepts of problem. Final section gives the conclusion based on our study and a brief discussion of implications for further researches close the paper.
