The household at Zilje 20 is named Mihelovi by the 1879 status animarum, as is the family next door at Zilje 19 whom we know as the Gornji Mihelovi — these two houses are related. The common ancestor of both families is Miha Čadonič, who is likely the source of these family names.
The originator of this household is Ivan Čadonič (Mihelov) who was born at the Gornji Miheli. He married Ane Balkovec and built the new house of the Dolnji Miheli. They had at least 2 children, including:
1A. Dora Čadonič b. 1805, m. 1823 to Jože Ivanovič (probably from Pavlini 5) — he moved to the Dolnji Miheli, changing the surname to Ivanovič
Dora Čadonič [1A] and Jože Ivanovič had at least 9 children, including:
2A. Kata Ivanovič b. 1824, d. 1894

2D. Magda Ivanovič b. 1837, d. 1884
2E. Ane Ivanovič b. 1840, d. 1886
2G. Niko Ivanovič b. 1846, m. 1886 to Mare Čadonič (Košutova) — they remained at this house
