Clarke of Scotland to Clark of Minnesota

William Clarke b 1646 Montrose NE Scotland d 1709 New Jersey, USA
Buried in Old Topanemus Cemetery in New Jersey next to wife Elizabeth Unknown

Son: Alexander Clarke b 1696 d 1730 New Jersey Buried in Old Topanemus Cemetery. Wife Sarah Van Gelder.

I have the line from William in 1646 to my Grandfather in 1905-1980.

I would like to hear from anyone that knows if Williams Father is Alexander Clark b bet 1619/1620 Scotland and that line as far back as I can go. Thanks R
