Most, probably all, lineages from indigeneous princes of the two Baltic
countries Latvia and Estonia before Baltic crusades, are legend-based.
The attestation of the lineages to the present day suffer from scarcity of
documentation of the 1200s and 1300s particularly, too. Late 1400s starts
to be relatively solid for reliable descent documentation of great landed
properties.
Sometimes it is unclear how the indigeneous magnate's blodline actually
could have survived in the early 1200s itself to even to the legendary or
semi-legendary, claimed forefather of a lineage of this sort.
One group of indigeneous tribes is Finnic tribes, such as Livonians,
Estonians (Ugaunia, Sakala, Ridala, Osilia...)
Another group of indigeneous tribes is Baltic tribes, Lati, Latvians, who
seem to have populated such principalities as Jersika and Koknese. Rulers
of Jersika and Koknese however may have been not of Latvian birth, but of
Varangian lineage.
There are some lineages who claim descent from sovereign rulers of the
Baltic tribes.....

Kaupo of Toreida (d 1217) was a historical chieftain of some Livonians and
he is claimed as ancestor of at least two lineages.
One of these lineages is the Livo lineage, given rise to the noble Liwe
family, later known also as Lievens.
Since chief Kaupo is chronicled to have passed his properties to the chirch
because he had no sons (or no male progeny) alive, there is a difficulty of
interpretation whether the Liwe lineage even may be descended from him in
male line.
One usual way to explain this is to assume that the actual forefather of
the Liwe lineage was Kaupo's maternal grandson. Another way is to interpret
that Kaupo meant none of his sons survived, but that there could have been
a son of one of his deceased sons, to be the actual forefather of the Liwe
lineage. The latter alternative suffers from the implausiblity of Kaupo
leaving a paternal gandson without inheritance of his landed properties.
Customary law seemingly was in favor of male-line grandsons. Not to speak
of emotional level......
In light of customs of those regions, it is easier to believe that maternal
grandsons might be left without landed inheritance in favor of church, that
is because maternal grandsons should be provided with landed inheritance
from the family of their fathers.
Kaupo's grandson in legend was one 'Nigu Livo', who would be father of
Gerardus 'Livo' (attested in 1269)
Gerardus' line (according to Elgenstierna, book IV, Lieven):
Johannes 'Lyvonis' (attested in 1292) as son of Gerardus
Loff (Ludo, Lu-Loff) Live (fl 1341)
Lideke Live (fl 1350)
Vinrik Live, lord of Parmila (near Kullamaa, in the Ridalan province of
Osilian dominion), mentioned in 1389
knight Lydeke Liwe, lord of Parmila (fl 1420)
knight Lydeke Live, lord of Parmila (fl 1471), two sons:
1 Johannes Live (d 1501 slain in war) - his great-great-grandson was:
Indrikis Livens, lord of Mazberzes muiza (fl 1631) in Zemgale, duchy of
Curland
2 Jyrgi Live, lord of Sooniste and Parmila (fl 1515)
2.1 Vinrik (Henrik) Live, lord of Parmila, Sooniste, Ubasalu and Teenuse
(fl 1563)
2.1.1 Reinol Live, lord of Ubasalu and Parmila (fl 1582; bc 1549; d 1619)
