I have a whole paper called "Meet the Raslers" It seems that Johann Henrich Roessler migrated in Sept. of 1750 on the Priscilla. He was among his brothers Daniel, Johann Georg & Conrad. Daniel Registered in the US as Daniel Resseler & Later was recorded living in Richland PA near John & George Ressler. So it seems they changed their names. Daniels son was known as Daniel Rasler Jr.(???) & that's how the paper says the name Rasler came about. I'm thinking that John & George Ressler were Daniels bros. Johann Henrich & Johann George that were on the ship. The Rasler family moved around to Indian & Iowa. I am a desendent of Phyllis from Iowa.
