I couldn't wait to get started on researching Mary Avery. More than that, I wanted to know everything I could about the Avery family. Who was Polly and when did her husband die? How many kids did she have? Where did they all end up? Were they all from Mentz originally? And more importantly: Did Mary Avery marry someone with the last name of Sly, and did they have a daughter named Jennie? How did the Van Burens fit in to picture? And what about George Avery?
Let's do a quick recap:
After ruling out any connection to the Martin Van Buren family, I had found 13-year-old Jennie Sly (likely my 2nd great-grandmother) living with James and Sarah Van Buren, and George Avery, in the 1870 census in Buffalo, New York. I had researched George Avery for a few minutes and found an Avery family living in Mentz, New York in 1850. George was 4 then. He was living with Polly Avery, presumably his mother, and quite a few siblings. One of them was named Henrietta. She may have been the same Henrietta living with George and Jennie in Buffalo in 1870. It was all starting to come together. This is the family tree sketch, based on the 1850 census.
Referring to the notes I had gathered on Jennie, I ruled Henrietta out as a possible mother for Jennie. That left Mary, born ca. 1836. Was she Jennie's mother?
It was time to get to work! My first search was for "Mary Avery, born 1836, living in Mentz, Cayuga County, New York".

The top result was what I had already found. The second result stopped me in my tracks. Sly? Was there really a Mary Sly in my search results?? This was the potential last name of Jennie's father, and the last name Jennie had when living with the Van Burens in 1870. Could it be?
Auburn and Mentz were both in Cayuga County, not far apart:

There was Mary! Mary Sly! Living with Polly Avery (her mother) and her 2 brothers, Thomas and Edward. And right underneath Mary's name was "Lucia J Sly, daughter, female, 8 years old (born ca. 1857), birth place of Illinois.
Lucia J.... not Jennie Louise Well, at least the initials matched!
1857 ... that matched what I knew thus far.
Illinois ... not New York. Huh.
I had originally started with 6 possible places of birth for Jennie:

After some sleuthing, I had narrowed it down to 2: New York and Ohio.

But that was before I had found "Jenny" in the 1870 census. That record listed New York as the place of birth. The New York 1865 census listed Illinois.
After finding the 1870 census, I had been leaning towards New York as the probable place of birth, but only because it meant that my "sleuthing" had been correct. Now I had to consider the source of the information on the 1870 census. I did not know yet exactly how the Van Burens were related to Jennie. Based on my notes, they were close relatives at best; more likely, they were distant relatives. In 1865, Lucia (if she was the same person as Jennie) was living with her mother and grandmother. That source of information on Jennie's birthplace was more credible. Maybe I had been too quick to rule Illinois out! I was back to 3 possible places of birth:

This question was on hand at the moment: were Lucia and Jennie the same person? I thought it was likely. In 1865, Lucia was living with Polly and Mary, with same birth year, and at least the same initials as the 1870 census. The name Sly only strengthened the case. I was excited. It was possible I had just identified Jennie's mother: Mary Avery Sly, born 1836 in Onondaga County, New York. My 3rd great-grandmother!
Of course, a new question was racing around my head: In 1865, Mary was living with her mother. Where was her husband? Was it possible that he was serving in the Civil War? Is that how he went blind?
Closer inspection of the census showed that Thomas and Edward Avery were both serving in the Army in 1865, yet they were still listed in Polly's household. If Mary's husband was serving in the war, why was he not listed, as well?
Was it possible that Mary's husband had died before 1865? If so, why was Polly listed as a widow, but Mary was listed as married? Something didn't quite add up.
It was another clue that there was more to this family than met the eye.
