Unfortunately I had to zoom out to put all of the family tree in one picture.
Russell had 2 full brothers, 2 full sisters, and a half-sister. It's interesting that Margaret went on to be a JW (i.e. stayed with the Watchtower organization), whereas Mabel, his half-sister, went on to stay with the Bible Students.
It would be very interesting to find the descendants of both Margaret and Mabel... wondering how many still are Bible Students / JW's...
In Schulz and Vienne's blog, it's interesting to see that so many deaths in Russell's family led him to know the Allegenhy cemetery well.
Look at the pictures and look at how the cemetery influenced Russell:
