Walter ABERLEY lived in Admaston which is the nearest village to Blithfield Hall and St Leonard's Church where his 9 children were baptized.
The only baptismal record for a Walter ABERLEY (within 10 miles) is on 1 Apr 1690 in Blithfield by Richard ABERLEY. We know that Richard also lived in Admaston from his wife Mary's burial record dated 29 Sep 1724 and from Richard's burial in 1725.
Walter may have been named in respect for Sir Walter BAGOT 3rd Baronet of Blithfield Hall (1644-1704).
Unfortunately there are also two burial records for Walter ABERLEYs in Blithfield (in 1692 and 1704) so it's not possible to be 100% certain whether Richard ABERLEY is the father of the right Walter. If either of these deaths related to a child then the father may have been mentioned so perhaps these were older Walters.
A Gabriel ABERLEY also lived in Admaston and was baptizing children at the same time as Walter, so it is likely that they were brothers.
Walter married Ann WORRAL at Colwich which is 3 miles west of Admaston.
The only burial record in Blithfield is dated 1780 which would make him 88 years old. Not impossible, but perhaps more likely that this record is for his son Walter or another relative.
A probate index for a Walter ABBERLEY of Colton is recorded in Diocese of Lichfield records dated 2 Mar 1716, so won't be this Walter. Colton is 1.7 miles from Admaston where Walter lived, so potential a close relative.
