Birth, Parent-Proof, Designation notes for Henry (Spouse 1)
We know Henry as the son of Nicholas from his mention in the various petitions filed after Nicholas’ death. He is designated N2.

Heinrich Mertz and wife Catharina appeared as sponsors at a 1779 baptism and Henry was mentioned four more times in the records of Longswamp, always a sponsor, never a father and always with wife Catharina. The additional mentions were 1782, 1788, 1790 and finally 1806. Thus, after the mass exodus of Longswamp Mertzes to Northumberland County, Henry was one of the few Mertz males left in Longswamp. He was in fact the only Mertz listed in Longswamp in the 1790 Census.

M L Kueker found on LDS film 1294878 (Butz) this information: Heinrich Mertz born 27 Jul (?) 1743 died 17 Jul 1821 son of Nicholas and Magdalena (is that a typo or is it an indication Nicholas had two wives?). He married Maria Catharina Heckman 28 Jan 1766. She was born 6 Dec 1746 died 3 Dec (?) 1821 and was the daughter of Peter and Elizabeth Heckman.

The Butz notes more or less fit with what I already knew about Henry. I knew his wife was Catharina and I knew he died before 7 Aug 1822. I didn’t think he had been born as early as 1743 but it does not contradict anything I know for sure.
Relocated and Census Tracking notes for Henry (Spouse 1)
Henry Mertz was listed in Longswamp Township in the 1779 Pennsylvania Septennial Census.

He was listed in Longswamp Township in the 1790 Census and he was listed among the taxables in 1801 in Longswamp.

I know this Henry lived to 1821, every mention of him always placed him in Longswamp Township, so the question is why can’t I account for him in Census after 1790? I have read the 1800, 1810 and 1820 Census listing of Longswamp line-by-line considering every possible mis-spelling; he is simply not there.

I have considered that he was the Henry Mertz in Manheim Township in 1800, 1810 and 1820 but the problem is in 1800, Manheim Henry was only 26-44 and this Henry presumably 57. I have guessed that Manheim Henry was this Henry’s nephew, N3a — but then what did happen to this Henry? And isn’t it quite a coincidence that Manheim Henry disappeared after the 1820 Census? On the other hand, I am certain that Manheim Henry’s wife was Maria Blatner and this Henry’s wife Maria Catharina Heckman.
Death and Find-a-Grave notes for Henry (Spouse 1)
Letters of Administration were issued on the estate of Henry Mertz of Longswamp Township to friend John Albrecht 7 Aug 1822.
