From the Hans Heinrich Reclam heraldry collection this card contains the arms from the Soll family from Amsterdam. J B Rietstap records the same arms in the Armorial General.
I am a little familiar with DNA but have not fully researched it. Do you know how many Soule have contributed to the DNA test? Has there been any close grouping from a variant of completely different name? If a DNA test is a match will you be alerted?
