Okay, now that figured out the deeds and trusts and other property document stuff let’s dive in with Ernst Hauser, owner of lots C, D, & E. In 1939, the survivors of Ernest/Ernst Hauser sold the lots to E.M. Aiken Inc.
The lots C-E appear to be what is now Mt. Sinai’s rear parking lot. On the Baist map shown here, the addresses appear to be 233-237 Q Street NW.
The deed has helpful information. The first person mentioned is William E. Hauser (aka William Hauser) and we are told he’s single. After Ernest F. Hauser (who is married to Lottie E. Hauser) we get another single guy Harry Louis Hauser. Then we learn Ernest Hauser is dead. And Sophia E. Hauser, a life tenant, died March 26, 1935.
