There is general agreement in the various sources that cover the Rockingham Martz family as to the names of John’s sons. There is not as much agreement as to their order of birth, but I believe the Masanutten book is totally consistent with everything else I have learned from tombstones and Census.

I believe Sebastian was John’s oldest son. He is designated S1a.

In 1820, Sebastian Martz is listed in Rockingham. A male 16-25 is present and one 45+. This Sebastian would have been 29. His grandfather would have been 45+ but he definitely had died. So it must be the younger Sebastian in Census, but then who is the older male?

As of summer 2015, there is no evidence of him on find-a-grave. However, he is listed in the cemetery database at Rockingham Historical Society. He was buried at the Martz Cemetery in the Mountain Valley area with the dates I show for him.

I believe Sebastian may have had a daughter Amanda born about 1825. She would be the young female age 5-9 in 1830 and then 15-19 in 1840 living with her widowed mother and then she was reported with her brother, I believe, Noah, in 1850-1870. She probably never married.

Sebastian had a son Noah, born in 1820, who would have been the son age 0-9 reported with him in 1820, then one of the two sons age 10-15 reported with Catherine in 1830 and the son 20-29 reported with Catherine in 1840, the age in 1830 being off by one bracket.

The Rockingham transcription of local cemeteries says that on Noah’s tombstone it says he was the brother of Marion and it also lists a Benjamin F Martz died 1891 who it says was the son of Marion and Lizzie.

But the only Marion I can find in Census was Noah’s son of that name born in 1854.

The Masanutten book says that Sebastian married Catherine Snyder, daughter of Valentine, 16 Feb 1819.

As of summer 2015, there is no evidence of her on find-a-grave. However, she is listed in the cemetery database at Rockingham Historical Society. She was buried at the Martz Cemetery in the Mountain Valley area with the dates I show for her.
