Alijda Joseph Joel Goldsmith (van Raalte) - Leah was her own 2nd cousin?

I just sat down and wrote this out. Two of Alijda's grandparents were siblings, making her parents cousins, and Alijda her own 2nd cousin. A third sibling in her grandparent's generation was also Emanuel's grandmother, so Alijda and her husband were also 2nd cousins.
