1876 marriage of my 3x grandparents - Petrauskas and Balvocius - Leckava

Received this great doc from my researcher, Vincas Bundza today. The doc identifies my 3x great grandparents.

Petras Petrauskas and Elena Norkute (Leckava)  // Juozapas Balvočius and Ona Perminaite (Maigai).

A few reasons this is significant for my research.

• Another hook into the Maigai area - near Vieksniai and Mazekiai.  See my posts at http://weekendgenealogy.blogspot.com/2015/04/ana-bavocius-butkus-vaicilius-of-maigai.html and http://weekendgenealogy.blogspot.com/2015/04/maigai-near-krakiai-vieksniai-mazekiai.html for more on Maigai.
• Zvingys is a fairly uncommon name.  MindaugasK has Zvingys and the same names in his tree as mine.  He is from Leckava.  We are also a light dna match.
• VirginiaM is a tight dna match of mine.  She is from Maigai.  Her father is a Perminis and her uncle, Jonas, is the one mentioned in http://weekendgenealogy.blogspot.com/2015/04/maigai-near-krakiai-vieksniai-mazekiai.html .
• Also note the number of Norkute living in Maigai.

Year 1876, 15 of May. Priest of Leckava church Bartkevičius registered marriage between peasant Leonas Balvočius, single, 29 years old from Maigai village Viekšniai parish and Ona Petravičiūtė, single, 19 years old from Buknaičiai village Leckava parish Viekšniai eldership.

Son of peasant Juozapas and Ona Perminaitė, legitimate spouses Balvočius and daughter of peasants Petras and Elena Norkutė, legitimate spouses Petrauskas. Witnesses were Kazimieras Šimkus, Antanas Tupikas, Antanas Krūtinis and others.

My trace into this is as follows:
Me > Christine Laukaitis > Bertha Laukaitis > Martha Balvocius > Ona Balvocius

Any ideas or thoughts, I'd love to hear them.

Thanks to my 'doc digger' Vincas Bundza...
