I-L803 (Y-DNA)

This project is for people who have tested and been assigned the paternal haplogroup I1a3a1d (L803) and also for people who are believed to have belonged to this paternal haplogroup based on tests done on descendants.

Defining Mutations

• L803

Origin

"According to Dr Ken Nordtvedt's calculations, the founder of L803 likely lived about 1250 y.b.p. (c.860). SNP testing has shown L803 to be downstream of Z58, Z59 and Z60/Z61/Z62." Surnames tested or presumed positive for L803 are Frame (A group), Hamilton (C group), Scruggs, Hay, Sinclair, Jobling, Prophit and Davis.

"During the same Walk through the Y (WTY) test in which L803 was discovered, an additional private SNP, L802, was found. The founder of L802 likely lived in the 1600s and is tagging one Frame family only.

"All of the men forming the larger, more genetically diverse FRAME A group who tested 37 or more markers are known to carry the RecLOH (Recombinational Loss of Heterozygosity) mutation, YCAII a,b=21 21. The typical values of 19, 21 at this site were converted to 21, 21. Further information on this type of mutation is found here. This special type of mutation occurs less frequently than the usual STR marker mutations and can only occur when the specific markers are on a palindrome region of the DNA chain, such as YCAII a, b. Since men in Frame A, Hamilton Group C, Scruggs, Prophit, Jobling, Hay, Sinclair etc.carry this RecLOH mutation, it indicates that their most recent common ancestor (L803) carried this mutation on his Y-chromosome."
