Hi Nancy, I haven't run across the Tarr surname on the marriage book yet. The only listings for DeHarpost are as follows: Number in() at end of listing is the page number of the book I am checking. Bk "D" pg. 196 20 Oct 1870 John Coy--Margaret Ann DeHarppard (51); Bk "G" pg. 35 25 Jan 1888 Frederick S. DeHarpert age 27--Mary M. Brockert age 27 (91); Bk "H" pg. 469 28 Jan 1897 John Q. DeHarpport age 46--Hester E. Morrison age 41 (110). I didn't find anything for Wm. E.; Lennie; Florence or Mattie DeHarpost or for Mary E. Tarr. Sorry, Bev Todd
