Contact set Answer
Nuxalk - North Wakashan Possibly as long as they have had general interactions (see earlier comments)
Burmese - Mon probably since at least the 13th century
Kambaata - Wolaytta since they settle beside each other
Langi - Alagwa At least for the last 100 years but probably also before this.
Papapana - Rotokas No earlier than the mid/late 19th century.
Maltese - Sicilian (modern) Since prehistory, documented since the 14th century.
Maltese - Sicilian (historical) Since approx. 1300 and still ongoing.
Ndebele - Tjwao Since they came into contact
Korandje - North African Arabic 500 years or more
Zaza - Turkish It is unclear.
Ipili - Hewa Likely, hundreds of years.
Marind - Marori Since pre-colonial times, probably for hundreds of year
Chipaya - Central Aymara Since they came into contact.
Temoaya Otomi - Mexican Spanish Approximately since 1950.
Mawng - Kunbarlang For at least the last few hundred years, more likely a thousand years.
Alorese - Adang Since the very beginning, when the Alorese settled in the Alor-Pantar archipelago (approximately in the 15th-16th century). The local origin migration stories on Alor narrate about a marriage between an Adang man, Mau Pelang, and an Alorese woman, Lai Muring Bali (Sulistyono, 2022; Wellfelt, 2016)
Bade - Manga Kanuri Although perhaps never not the most typical, mixed marriages do occur [today].
Muak Sa-aak - Tau Lü Not very long. From what my informants say, 20-30 years.
Sibe - Uighur ca. 1800 - present (ca. 200 years)
Toba - Spanish Since the migration and contact in the big urban centres, circa the XXth century.
Western Toba - Wichí At least since the 19th Century.
Paluai - Tok Pisin Definitely for several decades now, but I'm not quite certain when this started. I assume that it is closely related to the increase in mobility due to people relocating for education and work since WWII. There may have been a small amount of intermarriage with other Manus groups before that, but likely not much given that this is not culturally prescribed and preference is still to marry within the Paluai-speaking community.
Nen - Idi Generations. See response to other domains.
Burarra - Yolngu Matha For many hundreds of years, likely stretching back a significant period of time prior to colonisation in the late 18th century.
South Saami - NorwegianSwedish Presumably since the middle ages - the Norwegian king Harald Hårfagre had a Saami wife.
Yurok - Karuk Very little temporal information is available about contact between Yurok and Karuk speakers. Yurok and Karuk intermarriage is described in the second half of the 19th century, but presumably occurred prior to that as well.
Wutun - Bonan [Since the beginning of contact, the ming Dynasty period.]
