As a collector of 19th century images I occasionally come across a rare few with identification, and I always try to restore such images to their rightful descendants at cost plus shipping. The pictures in question are quarter plate sized tintypes, probably made in the 1870s. Neither plate has a case and both have suffered damage over the years.
Here are the details from the notes attached to the pictures.
(1) Tintype of couple IDd as
Denning Ibie Nehls Oct 13 or 16 1835 or 1836
Bertha O. Richter April 18, 1843 or 1844
My great grandparents, Mother's maternal grandparents. Great grandmother made the hair seed wreaths. It is her Bible that Tom Moehl has. AMF
(2) Tintype of two girls and one boy IDd as
Lydia Anna Nehls 2-2-1866 (Large cameo was her mother in laws engagement pin)
Martha Amelia Nehls 3-16-1861 (Small cameo and chain her engagement gift)
William Herman Nehls 6-25 1867 or 1868
Martha A Nehls Wirth is my grandmother, Mother's mother. AMF
If you believe these people to be your ancestors please contact me about restoring the tintypes to the family. I offer this because I hope someone will do the same for me someday.
