Hello Shelley,
I'm afraid you have some of the SPACE lines mixed up. The family that started the Space Farms at Beemerville are descendants of Peter SPACE, born before 1744 in Germany, who with his brother John, born 1757 to America and settled in NJ. Their descent is as follows: Peter (the immigrant) >Peter (the son) >William Britton or Bertram >Fred Van Auken > Ralph (the founder of the museum and a brother of the Parker you mentioned) > Fred (who now runs it). There are still a lot of the SPACE lines I wish we could sort out.
