My name is Scott Small and I, too, am a great grandson of David Yavner thru Sadie Pauline --> Harry Small.
I have been working with a cousin on my Small side and have neglected the Yavner side of my genealolgy, especially the second and third generations here in the states.Living in Boston, I have picked up a lot of info from Mass Vital Records and gravestones in Beth-El Cemetery.
I have a few different dates for you but feel free to correct me.Harry Yavner DOB per gravestone is 5/15/1889.Harry's wife, Celia, and Toby's wife, Ella, were niece and aunt (per my dad).
Sadie's DOB is probably 10/30/1890.
Max's wife, Sara nee Feinberg 7-10-1887 to 7/27/1976.Married about May 1920 per Boston Jewish Advocate.
Ben Yavner married Harriette Pearl Freedman (10-2-1899 to 3/14/1961).
Henry Mintz was 9/22/1899 to 8/26/1972.
I have 8/29/1974 for Lewis Siegel's DOD.
I will assume that you are Franklin's son.
I will be grateful for any and all information for any and all siblings, spouses and children after the first generation.
Thank you for the information that you already provided.
