A spinney by some brook

This poem needs some extratextual context, I think. My wife and I were doing some research into my (Frisian) family on my father's side - I have hardly no knowledge of them at all (my real grandmother died in 1938 and my grandfather in 1963 when I was about 3,5 years old). We found some weird stuff: my greatgrandfather had a twin brother who died at the age of 1 month. When we were looking into his atrologogical birth chart, we decided we needed that of his wife too. When I saw the latter  birth chart, I had a cold fright, which I cannot explain other then a feeling like: oh no, not her again. We then off course checked for my grandfather Jan (Dutch version of John, so yes, I am named after him). We found that there had been an earlier son Jan, who was born on Oct 27th 1885 and died on March 23rd 1887. My real grandfather was born March 9th 1888 (feels like a replacement son to me). When we checked both the birth chart and the chart of the day Jan 1 died (yes, March 23rd is my birthday, 73 years and 8 hours after his premature death of which we have not been able to find a cause) we found some very strange correlations with my birth chart that have totally freaked me out (as I am a Womb Twin Survivor - there should have been a twin brother for me). It is almost as if Jan 1 and me, we come from the same soul, that I am somehow a reincarnation into the same family of Jan 1, which I find hard to accept, even though I am almost sure that there have been past lives for me. Anyway, the bits that I knew about my real grandfather seems to make much more sense now (and possibly  I understand my father better too - he knew about this history of an earlier Jan, apparently, but never told me (so my stepmother informed me). Yesterday I did a tarot spread and weirdly got the Death card in the spot directly to do with Jan 1 in my daily life (Death = Transformation and linked to Scorpio in Astrology - under which sign Jan 1 was born... Help!😅)
