A 1950 Detroit border crossing manifest card records Catherine (Kathrya) Margaret Ponceby, born in Edmonton, Alberta, on 7 June 1927, entering the United States to reside permanently with father Donald Ponceby at 9715 Logan Court, Cleveland, Ohio. She may be Donald Edwin Ponceby's daughter, stepdaughter, adopted daughter, foster daughter, or another relative using the Ponceby surname; the same card names Peter Cook of Cranbrook, British Columbia, as her brother. A Cuyahoga County Probate Court marriage index entry for Kathryn Margaret Ponceby and Robert Ray Johnson may be the same woman under a variant spelling, but it does not name parents, so the identity should remain a lead until corroborated.

Why this is not settled yet
1927 –
Is Catherine/Kathrya Margaret Ponceby Donald Edwin Ponceby's biological child, adopted or step child, foster child, or another family member?
What record explains the Peter Cook brother relationship while the passenger is recorded with the Ponceby surname and father Donald Ponceby?
Does an Alberta birth, adoption, guardianship, immigration, nursing, marriage, obituary, or naturalization record identify her parents and mother?
Does the full Cuyahoga marriage record for Kathryn Margaret Ponceby and Robert Ray Johnson name parents, birth date/place, residence, or prior-marriage status that ties her to the 1950 border card?
How should this lead be reconciled with the indexed 7 May 1927 death of Catherine McKay Ponceby and the existing Horne/Mackie/McKay identity conflict?
Notes
Notes
Lead created from the proposed 1950 border crossing manifest card ingested on 25 April 2026.
The card's birth date is interpreted as 7 June 1927 because the form uses U.S. numeric dates elsewhere and gives age 22 years 9 months on 28 February 1950.
On 25 April 2026, a Cuyahoga Probate marriage-docket search found Kathryn Margaret Ponceby as bride and Robert Ray Johnson as groom in case 1900ML635049, volume 392, page 0510. The docket uses 1900 as a historical placeholder and does not state the actual marriage date.
Do not create a person record or update Donald Edwin Ponceby's canonical relationships from this single proposed source.
