Talk:Avunculate marriage

I happen to know of a case, recounted in the Reader's Digest book on Canadian law, in which an uncle married his niece by adoption. The family tried to have the marriage annulled because of the supposed blood relation, but the court ruled that because the girl was not a blood relative of her husband, the marriage was valid.70.26.8.139 (talk) 03:51, 21 May 2017 (UTC)

In Canada these marriages are legal, please add the folowing citations to Canada. https://www.cbc.ca/news/technology/repeal-laws-banning-cousins-from-marrying-geneticists-1.752965 and https://laws-lois.justice.gc.ca/eng/acts/M-2.1/page-1.html — Preceding unsigned comment added by 2607:FEA8:3C60:183B:69C9:CF11:D702:17FC (talk) 18:47, 2 February 2019 (UTC)

Alois?
Article reads: Alois Hitler and his niece Klara Hitler, parents of Adolf Hitler. After they were married, Klara still called her husband "uncle".(1885)[15][16]

First, Alois Hitler was born illegitimate and nobody knows who his father was. There are several candidates, as explained on Wikipedia’s own Alois Hitler page, but they are just guesses. If you want to include him on the list, at least say it’s speculative.

Second, Assuming Georg Hiedler was Alois' father, Klara’s mother Johanna was Alois’ first cousin not sister, so he and Klara were first cousins once removed, not uncle and niece. I see on the list you include half-uncles and grand uncles, so first cousin once removed is not unreasonable, but at least call it what it is.

Third, As for Klara calling Alois "uncle," that title is properly used for the brother of one's parents, but can be extended to any male adult of one's parent's generation: first cousin, second cousin, half-brother, etc. 71.162.113.226 (talk) 16:20, 30 January 2021 (UTC)

consequences
You have quite a long list of examples. Maybe you think it frivolous, but you might also include some practical consequences of uncle/niece marriages. Suppose they have a child named Joe. Joe’s mother is also his first cousin, while his father is also his grand uncle. Joe’s maternal grandfather is also his uncle, and if this grandfather has other children, they are Joe’s first cousins as well as his aunts and uncles. 71.162.113.226 (talk) 14:48, 29 December 2020 (UTC)

Trần Hưng Đạo & Princess Thiên Thành Section Removed Due To Potentially Inaccurate Information
Trần Thái Tổ likely died even before the princess was conceived, and she was born over a year or two later after Trần Thái Tổ died. Additionally, the only reason why princess Thiên Thành was thought to be Trần Thái Tổ's daughter was due to the fact that one of her titles was "長公主", which was usually applied to the sisters of the reigning monarch. However, this practice was not consistent—sometimes, the eldest daughter of the ruler would receive that title, as seen with princess Trường Ninh of the Trần dynasty and the Three Kingdoms Period of China.

Trần Thái Tông had at least one or two children before princess Thiên Thành, and at the time he was already married to over one woman at a time, making it highly doubtful that Trần Hưng Đạo was her nephew. Rather, due to the age gap of prince Yên Sinh (Hưng Đạo's father) with Trần Thái Tông and few remaining records about Trần Thái Tông's maternal side, they were half-brothers. This meant that more princess Thiên Thành and grand prince Trần Hưng Đạo are paternal half-cousins. Narcotic Epiphany (talk) 03:50, 28 July 2023 (UTC)
