| Nuxalk - North Wakashan |
Around one millennium

| Burmese - Mon |
1000 years.
|
| Papapana - Rotokas |
IF exchange has occurred, it would have started no earlier than 1860 when Papapana ancestors were part of a migration from the south. Most likely, exchange would have started after 1894 when Papapana speakers finally settled in their contemporary location. Papapana and Rotokas speakers still practice exchange in the current day.

Two centuries up to the present but only in the context of trade and ritual matters, never in the form of intermarriage.

|
| Muak Sa-aak - Tau Lü |
It is not frequent, but there are at least a few people in each village married to a Tai Lue person, and there are people who have married and moved to Tai Lue villages. However, based on what my language informants are aware of, it seems to be a recent occurrence- beginning with people now in their 40's or 50's.

Contact is presently ongoing.
|
| Western Toba - Wichí |
Western Toba and Wichí people practised exchange since they met one another. Neverthless, we have historical information since the 19th Century.
|
| Nen - Idi |
The Williams ethnography has data from 1920, and six generations will have been claimed from then. So if we say each generation is about 20 years, then contact has been ongoing since at least 1800. But I imagine contact has been ongoing for much longer than that.
