(1) I learn that my paternal grandmother's _father_ was a total dick, so much of a total dick that shortly after my grandmother and her twin sisters married, their mother turfed him out. Given that this was sometime in the late 1920s or possibly the first year or so of the 1930s, quite surprising. Because of this, even tho I have a highly detailed and well-sourced genealogy for my paternal grandmother's _mother_, the details on her father are utterly lacking. No birthdate, even. My cousin told me about the dickishness.
(2) I became frustrated at some other part of the tree I was working on, and decided to find out if that particular great-grandfather remarried. My thinking was, it all happened in Washington state so I had good odds of finding a remarriage. Also, I had a mystery alternative wife name for him that I was curious about. Off I went to Washington State's Digital Archives to find Henry's marriage records. And there were _three_ of them. Wow. I filled all that information in and didn't think too much more about it. (Yes, it did solve the mystery alternative spouse issue.)
(3) In the course of looking at Henry's marriages, and trying to find out if I got them all, I stumble across a marriage involving CPH Abbenhouse. When I look at the record, it is signed by Henry and by Henry's then-brother-in-law Pieter. This can't be a coincidence. Who is CPh?
(4) I fail utterly to find any indication of C (I'm assuming Cornelis) P (I'm assuming Pieter, and wrong) H (I'm assuming Hendrik, wrong again, it's Ph for Philip) in genlias. I find out Amsterdam isn't in genlias and try the Stadsarchief. I fail. I double check where the Abbenhouses come from, realize it's Gelderland, try _that_ archive, fail again, but discover that only the marriage records are in genlias and a few death records. So I no longer expect to see CPh in genlias. Still, he could be a cousin or something.
(5) I find out that CPh says he's headed to Bow on his ship entry. That's promising.
(6) I find a death record for Cornelis, but none for his wife. I find numerous possible offspring and contact what I believe to be a granddaughter (yup) on facebook. She agrees we are likely related. I still, however, have no certainty about the nature of the relationship between Cornelis and Henry.
(7) I return to the Fount of All Relevant Wisdom (after pipl, of course), the Washington Digital Archives and start looking at every Abbenhouse I can find. I learn that Mother Abbenhouse came over, and died here. That's looking pretty promising for the boys being brothers.
And (drum roll please), then I turned to the Seattle Times archive. I discovered so many hilariously sordid entries when searching for my mother's brothers that I thought, what the heck, let's see what I can find for these relatives. In addition to a very respectable bunch of articles about a principal at the super cool Surrey Downs and Ardmore, I found Ruth's obiturary. Very nice: I now have proof of the four boys (which I was reasonably certain of, based on the fb interaction). And then, for the win, the obituary for Mother Abbenhouse, my paternal grandmother's paternal grandmother:
Seattle Times obituary 7 Nov 1932

How unbelievably cool is _that_? Heintje is a diminuative; I have her marriage record and some records for her children's births from genlias.
