Who Was Lettie Riffle's Father?

How I label things here: Proven means a record I have seen supports it. DNA-supported means shared matches point to it but I have no record that names the relationship. Hypothesis is my best working idea and is not settled. Ruled out means I tested it and it failed.

The story so far

Isalata Lettie Riffle (1877 to 1925) is my second great-grandmother. She married Ora William Murray, a son of James Murray and Harriet Spencer, and they raised a family whose descendants include my mother. Her mother was Minerva Riffle. Riffle is Minerva's maiden name, and Lettie's father is the only parent in that generation of my tree that I cannot identify.

The wrong fathers on Ancestry

Many online trees name Joseph Brooks or Daniel Webber as Lettie's father. I tested both, and I have ruled them out by age: they were about 12 and 11 at the time of Lettie's birth.

Minerva's brother, Francis "Frank" Riffle, is also attached as Lettie's father in at least one tree, marked with question marks. I know Frank was Minerva's brother, so he is Lettie's uncle and not her father.

Why a wrong attribution matters

This is more than a tidy-tree issue. When thousands of trees point at the same wrong father, Ancestry's ThruLines and similar tools treat that man as the likely answer. Shared DNA matches then appear to confirm a relationship that does not exist, because the matches come through other lines. The wrong father also blocks the DNA-based search for the right one. I have been writing to the tree owners politely and asking them to detach the father and leave the line as unknown, which is more accurate than a guess.

What I am doing

1. Asking tree owners to detach unproven fathers, and giving the reason with the age evidence.
2. Using DNA clusters that descend from Minerva Riffle's other lines to find matches that do not come through Minerva, because those matches may come through Lettie's father.
3. Looking at records near Lettie's birth in 1877 for a household that includes Minerva, a bastardy or support record, a marriage, or a neighbor who is a DNA match.
4. Looking at Lettie's own documents, including her marriage record, death record, and any obituary, for a father's name.

For researchers with Riffle ancestors

If you have Riffle ancestors in a tree you maintain, please check whether Lettie is attached to a father without a source. If you do, consider detaching the father until a record is found. A blank is better than a wrong name.

My pledge on this site is to separate what I can prove from what I only suspect. This page is an example of that rule at work.
