Did Vinnie Ream visit the White House daily for 5 months?

Eva, I have been trying to find independent verification of her story; if I can find this my doubts will be erased. I checked Tom Pendel's Thirty-Six Years in the White House. He was the chief doorkeeper for Lincoln's White House. No mention of Vinnie Ream in that book. I also checked Through five administrations: Reminiscences of Colonel William H. Crook, body-guard to President Lincoln. Crook writes about Tad Lincoln and others who were in and about the White House, but no mention of Vinnie Ream. Additionally, I checked Recollections of Abraham Lincoln, 1847-1865 by Ward Hill Lamon. Lamon is the one who allegedly came upon an entrance to Lincoln's office that kept Mary Lincoln from knowing about Vinnie Ream's daily visits. No mention of Vinnie in Lamon's book.
