I'm pretty sure the Clarke ellipsoid was produced without any US data,
but rather used
various arcs measured in Europe and India. Hayford and Bowie adopted
it for the US datum much
later, even though Hayford had by then produced his own estimate for
the ellipsoid--this may
just have been a matter of convenience, since I think it was first
used in the US in the 1880's.
All moot at this point, anyway.
