His son (?) having been a printer is the only clue I have to Erasmus Kleboe's trade in Castle St East. An Anna Maria d of Rasmus Kleboe was baptised in Norway in 1783, and a Rasmus Kleboe was married in Norway in 1745, and in Denmark in 1762.
Erasmus Kleboe, Soho tailor
Erasmus Kleboe is my 4 greats grandfather. By 1803 he had moved to 52 Gerard Street where he payed £4/6s/8d tax. This might have been a bad move because four of the six Kleboes died within 14 months, only Bergette and son Andreas survived.
Erasmus' mother, Ellen Maria Kleboe 1728 - 1803, lived with him at Gerard Street, her cause of death was 'age'. Erasmus and his daughter Elizabeth were buried on the same day, June 12th 1803, at St Anne's Soho. When the churchyard was cleared in 1891 the family's bones were taken to plot 1 Brookwood Cemetery near Woking on the Brookwood Necropolis Railway.
Three years after his death, 30th April 1806, the London Morning Chronicle carried this: 'Creditors of Rasmus Kleboe Taylor (sic) late of Gerard Street may receive a further dividend of 3/6d in the £' so Erasmus was presumably a tailor. Bergette married Edward Humphreys Robnet on 30th December that year.
