Hello, I have another name for you to add as a possible daddy for your Adam.
The records for Bern Reformed Church in Berks County show " 1779 Dec 25 Speth, Joh Adam. Henry S. & wf. 1778 Aug 14.
I am desceneded from Henry through another son, Philip.My line americanized their name to "Spayd" but other family members took on the names Spotts or Spatz or Specht.I do not have a complete record of Bern Church baptisms.
I believe that the Sebastian that you mentioned was a cousin of my Henry.They lived near each other in Heidelberg Township for many years, and sponsored each others children.In these early records, the names were spelled by whoever wrote them down, and Sebastian and Henry's names were spelled alike according to the early records.You will find them living near each other in the 1790 census, and their name was spelled "Spead".The following paragraph is from the Morton Montgomer Annals of Berks County.
"Charles E. Spayd, of West Leesport, Pa., was born there Feb. 10, 1860, son of Samuel and Susan (Gauger) Spayd and a member of a family that was planted in this country in 1753, the date of the arrival of the emigrant ancestor on the ship "Rowand." In 1790 the Federal census records Henry, Sebastian, John and Philip as taxables of Heidelberg township, Berks county. Henry Spead had three sons under sixteen years of age, and two daughters; Sebastian Spead had one son over sixteen, three under sixteen and three daughters. John Spead was married and had one daughter."
I believe that Henry and Sebastian traveled from Heidelberg Township, to Bern Township to go to church because of the connection of family.The minister who baptised Adam was Ludwig Lupp.He was also a passenger on the Snow Rowand with Henry, and he was married to Anna Maria Spath. I believe she was a sister of Henry.
Please notice that Adam was baptised on Christmas day.I believe this was done at a family gathering.Henry served in the Militia during the Revolutionary war, in Captain Filberts unit.He may have been gone for the year and four months between Adam's birth, and his baptism.
Finally, The Annals of Lebanon County has a biography on Daniel K. Spayd, another descendant of Henry's.Of him it says "John Henry Spayd, father of Daniel Spayd was born in Germany, and came to America a lad of 16 years."
This family named all of their sons Johannes and then the middle name was used as te individuals name, unless their name was to be John, in which case I don't think they had a middle name.
