In British Guiana, the Chinese did not maintain their distinctive physical features due to the high rate of Chinese men marrying people other ethnicities like Indian women. The severe imbalance with Indian men outnumbering Indian women led some women to take advantage of the situation to squeeze favors from men and leave their partners for other men, one infamous example was a pretty, light skinned, Christian Indian woman named Mary Ilandun with ancestral origins from Madras, born in 1846, who had sex with Indian, black, and Chinese men as she married them in succession and ran off with their money to her next paramour, doing this from 1868 to 1884. Indian men used force to bring Indian women back in line from this kind of behavior. The most severe lack of women in all the peoples of British Guiana was with the Chinese and this led Europeans to believe that Chinese did not engage in wife murders while wife murders was something innate to Indian men, and unlike Indian coolie women, Chinese women were viewed as chaste. Chinese women were not indentured and since they did not need to work, they avoided prospective men seeking relationships, while the character of Indian women was disparaged as immoral and their alleged sexual looseness was blamed for their deaths in the "wife murders" by Indian men. The sex ratio of Indian men to Indian women was 100:63 while the sex ratio of Chinese men to Chinese women was 100:43 in British Guiana in 1891.
