Graceland,
He is a half fourth cousin, or maybe a fourth half cousin !!
I went to this site:
http://www.shtetlinks.jewishgen.org/krakow/relations.aspand in the second box "additional relationships" I selected "show all relationships"
The chart tells me/us that relations of siblings of g-g-grandparents are fourth cousins, so step-relationships are "half" the full monty !
There is also an chart for half-relations, but that only goes up to grandparents ... but it does distinctly say "half cousin" !
Nick, the "show all relationships" chart clearly shows the 1st, 2nd 3rd. relationships and the once, twice ... removeds
There are actually two groups of "removeds", the simple one is:
My cousin is my cousin (no removals !)
my cousin's kids are my cousins, once removed,
their kids are my cousins, twice removed,
etc
the other one is towards the top right of the chart, but I don't know how that is defined (in words !)
Hope this helps !
