Larik and Darik, the Oaks of Alps, and Akemantak - Softshoewood

LARCH: Old High German *larihha, from Latin larix (genitive laricis), probably a loan-word from an Alpine Gaulish language, corresponding phonologically to Old Celtic *darik- "oak". Darik stems from the same root as TREE itself, derived and generalised from oak-names.
Thus, *Larik- mirrored *Darik- in an ancient Celtic language. Did other tree names sound as -ARIK in alpine communities? Darik, Larik, *Barik (Oak, Larch and Birch?). A sonorant descendant of Darik is Welsh Derw (der-u), "oak", akin to Old English Treow (Tree).
Back-constructed, without the recent loan from German into English (larch < Lärche), the English word larch could have become LARROW in a straight path from Old English.
I eat yarrow under the larrow, and it warms me to my marrow. Yes, precious. I do.
North American tamarack (red larch) is likely an Algonquian loan (1805) (cf. synonymous Hackmatack, 1792, from a source akin to Abenaki Akemantak "supple wood for making snowshoes").
Larches lose their needles. They are conifers, but NOT evergreens. Magnificent.
