I tried looking but there are too many Harry Kearns born around that time. Any idea of his parents' names or if Harry is short for something else.
Sorry, I hate answering questions with questions.
Dear Mr. Kearns,
Thank you for posting your request on History Hub!
We searched the Maryland Births and Christenings index on FamilySearch and the Maryland Births and Christenings index on Ancestry but were unable to locate a Harry Kearns. However, the Maryland State Archives has birth records for Baltimore City that are available online; here is a link to the birth record index for 1887-1891.
We hope this is helpful. Best of luck with your family research!
