Domingo had no known connection with the Chilembwe uprising but, in its aftermath, he came under suspicion and his correspondence was intercepted. In January 1916, after replying favourably to a letter from Booth advocating African political representation, he was required to leave Nyasaland and was sent to Chinde as a clerk but was transferred to Zomba in 1917. In 1919, he was allowed to return to Mzimba district, where he worked until 1927 as a government clerk. He then returned to preaching and teaching in the Seventh-day Baptist church until resuming work for the government in 1934. Nothing further is known of his history, except that he occasionally communicated with the Seventh-day Baptists in America until his death some time in the late 1950s.
